I was speaking to a Tmobile rep on the phone who couldn't go into details because of a recorded line, but mentioned that the HD2 can run on the 4G network. He said there are "ways that will not void warranty". He said to just search and I will find it. It was not a hardware limitation, but a software one. Anyone have an idea on this?
Cmon bro, you have over 1300 posts and you think the HD2 is capable of 4G and that it's a software limitation? Secondly, even Tmobile themselves dont even know what 4G is with their subliminal ads, what make you think any of their reps know any better?
HD2 doesn't run on 4G and it's a hardware limitation period

What does my post count have to do with what a t-mobile rep says? I merely posted what I was told via a chat with a rep when I questioned him about their 4G service.

Yes the hd2 is hardware limited to 7.2 Mbs but since hspa+ is backwards compatible T-Mobile's "4g" network will make a difference to you connection... Idk what the Rep you talked to was talking about but frankly he's f.o.s (full of $#!+).. the hardware radio is limitation!!!

Thats what i figured. I know when HSPA came out, it was "labeled as 4G speed" but called HSPA. Maybe that is what he was confused about since now Tmobile is trying to actually have a true 4G network. Who knows. HSPA is good for me now anyway.
after the 3.14 update they'll release one that's 4.0 meaning 4g and the hd2 will then have 4g ....lol
What a douchebag, I hate phoneshops, most of them would tell you everything you want to here, just to let you buy one. When I went for my hd2, I had to buy a display model because there were none left, and the guy behind the desk had one too, an hd2. With a cooked rom. I asked to run the phones init process before taking it home, and it got stuck at sim recognising, we tried multiple simcards, everything failed, that guy was also a douche, he said immediatly, sold is sold. Maybe he tried to customise his hd2 and when it failed, he swapped it with the store display model. Luckely for my another employee overthere said he couldn't make it, if it was up to the first seller, I had to send it to repair,that dumb prick. The other one gave me a cheque to buy it in another store, where I asked the same thing, point is, always try before you buy, and insist, you are customer, and king.
Im not too familiar with all this phone junk... I mean when you guys are saying its a hardware issue, to me it sounds like you guys are saying a Dell c600 oldschool laptop only being able to run on dial up... DSL outta the question... hahaha...
i do believe it is probably a software issue, but i havent researched it much...

Even in a smartest of smartphones you can not change the radio module, like adding a modem in the cheapest laptop, different class of gadgets.

so did your statement about hspa+ mean that the phone takes full advantage of the bandwidth available in hspa without any software mods?
T-Mobile doesn't even have real 4G. Hell, they don't even hardly have 3G where they say they do, let alone the "largest 4G network in America"
What a load of crap.
No, our totally awesome HD2's will not run 4G speeds, unless you know some sort of black magic or voodoo.
HSPA + uses the same frequency as the 3G one.. so even though its the same AWS band the hardware must be able to reach the Max speed avaible... it would be like having a 1Gig/s line but it only reaching 100mbs since that's the hardware limit... Now in some cases hardware is capable of more but limited by the firmware.. take for instance wimax modules, there capable of LTE but don't have the supported software...
Sent from my HTC HD2 using XDA App
It is very likely they were referring to 3.5G (H) instead of 4G.
Actually T-Mobile does not really have 4G yet that could be comparable to Verizon for instance... yes, it is fast on Galaxy phones but overall it is just fast fast connection... 3.75G I guess ... however, my HD2 works on 3.5G (H) connection just fine and I am subscribed to 4G 200MB plan for $10...
Will HD2 work on real 4G... cmon man don't make me loose calories by typing what 1300 threads already state... NOT HAPPENING!

I'm not commenting on whether 4G is possible or not on the HD2, but rather on your comment above.
They advertise Android phones don't they, yet that's possible on the HD2. They advertise WM7 phones, yet the HD2 can do that too. I know a lot of things on the HD2 were said to be impossible and later it was proved possible either through software changes or even just enabling a registry setting. Cell companies limit features of phones all the time by not including certain software or not enabling certain features as a way of differentiating phones. So as far as your comment goes, it means absolutely nothing.

Sweet. I think on my HTC g2 never hit that
HTC HD2 updated .zip rom EVO 4G (not working. no problem...)
Doesn't matter if 4G network not works onto HTC HD2,because when more people buying a 4G phone than they are using 4G network and after few months (maybe) year than 3G is also faster as before. 3G networks can used and functionally better onto internet whitout changed when 3G is full than you automatically down to almost historic G networks. When time is there i sell a new smartphone with 4G,but my old HTC HD2 is ever working (when it rains and not rains). I like this crazy phone. Unbeleaveble
HD2 doesn't run on 4G

Why is it that all the coolest gadgets get to one of the worst carriers first? I love the specs of the Supersonic (EVO 4G) or whatever you want to call it. The problem is with Sprint. I've tested HTC EVDO products (HTC Titan) back to back with HTC GSM products (HTC TyTN). The CDMA products suck battery life much more quickly than the GSM products. If found this on almost every Sprint and Verizon CDMA smartphone. This is probably why the the Supersonic has a larger battery.
Also, it is true that some CDMA products do not allow simultaneous data and voice transmission. This may not be true of this device because it will be able to do CDMA for phone and WimaX for data. I am very interested in this device but I'd be much more interested if this device were on AT&T or even T-Mobile.
I am loving the HD2 running on AT&T. But I'd love more internal memory, the front facing camera, the kickstand, the better camera, etc.
sprint is the cheapest carrier, but valid point with battery useage. I also don't particularly like having to get an "OK" from sprint to change phones. Wish you could use a SIM card.
question though... how often are you browsing the web or using data while talking on the phone? I can't think of one instance in my past 10 years with a cell phone that I needed data while talking. If you're on the net, your data gets put on hold untill after your phone call is over. Back when I had dialup, my phone service offered a similar feature, and cdma does the exact same thing.
As far as everything else, speeds, coverage, dropped calls, annoying but I hear complaints from customers from all the different carriers, it's a cell phone thing.
OH! and where's my damn sprint iPhone? I'm calling BS on cdma getting all the cool toys... I had to wait a year before sprint finally got an android phone, while t-mobile / att had all types of phones that could be used on their network *rage*
let us have our moment in the spotlight for once.... sheesh
hold on boy
i think sprint is the better than att all the way. at least here in San Francisco.
The plans are better than att.
i have friends with their iphones and their internet sucks compare with my htc pro 2 on sprint.
And htc evo data details.
4g + data= Works
3g + data= No
wifi+data=Works
I can't wait for this phone.
No matter what carrier get the cool things first there is always some spoiled brat shouting out loud.

And this @ OP.
I really really hope there is a GSM version coming out soon.
lol there is gonna be a GSM version no doubt. there will definitely be a variant of the Supersonic(aka EVO 4G here in the US for Sprint) in Europe/overseas NO DOUBT that you'll only be able to use on EDGE here but there will probably also be a GSM variant here in the states for another carrier that is basically the same phone but a little different and with different radios or whatever. an example would be the supersonic for t-mobile, lets say their first HSPA+ compatible phone or something, they call it whatever they want and HTC basically makes it for them using the core parts of the supersonic and keeps everything like android and whatnot and just changes up the radio and changes CDMA to GSM and puts in tmo's 3g bands in the radio, and whatever other physical changes t-mo may want like the buttons and whatever.

Last time i checked, Sprint (and by extension CDMA) usually gets last dibs on the cool phones. Name them...Touch Diamond/Pro/Pro 2, HTC Hero, Nexus 1. They never even carried the Touch Diamond 2 till today.
it is true, I wish there were sim cards.. but other than that, in the bay area, sprint kicks ass!
I have never gotten one dropped call since I got my hero, and I talk 2000+ minutes a month. I have 3g almost everywhere.
Also, no matter what people say, sprint has amazing customer service. I mean, at least you don't get put on the line with some indian guy half way around the world who just tells you to turn your phone off then on again...
oh and, at&t just sucks... no matter what hahah I'm glad sprint is stepping up to the plate. they offer amazing deals, great phones (as of now) and I think, are starting to move up in the world

AT&T does suck, but I'm stuck on them. I use Sprint for my data service (aircards FTW) and they have AMAZING customer service. Whereas AT&T just *****es about everything and tells you how wrong you are, then tells you how happy they are you stay them. If they didn't have such fast 3G (which in my rural area isn't crowded, so it is reliable) I would switch to Sprint in a heartbeat. Too bad EvDo pretty much sucks

Or the Nexus
I think the battery suck issue is not so bad given the fact that you can get almost unlimited voice, data, and messaging (of all sorts), plus turn by turn GPS+traffic routing, for $70/mo, less with discounts.
Where's AT&T or TMo's 4G network? I don't hear them actually deploying LTE in any other market other than testing. Kudos to Sprint... psyched for EVO.
ok, so the deal with this phone, ive been reading up on the specs, 4g (6mb/s) is 10x faster then 3g(300mb/s) i run off clearwire internet witch happens to run off the same exact wi-max as sprint and let me tell you, it is FAST. the processor in the phone is a massive 1ghz! for a phone, thats a overkill, plus 588mb of ram... i cant wait to try to overload this phone... probaly take 50+ apps running at once... 4.3 inch touch screen, 8 mega pixel camera, android 2.1 (unless they release a update before the phone is released) i say all in all this phone is going to be by far the fastest android phone on the market, and PS: the HTC HD2 IS the same exact phone just running WinMo 6.5, slightly better processor but clocked the same, same ram, same screen size, its the same phone with a slightly different button layout.

Wrong OS, mate.
he did say "variant"
as in its not exactly the same but close, a knockoff, cousin, whatever. everything is almost identical spec wise just the os is different. thus its a variant. if GSM'ers want the evo in a gsm model. you could help with the port of android to the hd2. just a thought.
.
It's not really a variant. The OS makes them completely different. One is full of future; another is just about dead. Unless someone could port a high quality and well tested Android into it, then it would be a different story.
Well I the closes variant to the Evo 4g is the Desire or Nexus One. If you can do away with the 4.3 inch screen, 4g Wimax, 8MP camera and the extra memory. Well the year is young, so who knows.
Sprint is great in Minneapolis.
Come to papa Evo.
me(US T-MO) and my friend(sprint) wondering if any of u know if the HTC EVO 4G gonna have the worldphone compatability(GSM slot for gsm networks).my friend currently using the TOUCH PRO 2 from sprint and he has the ability to switch the phone to GSM carriers.jus wondering if the EVO gonna have the compatibilty.if yes defenetly dropping my HD2.
The Evo 4G is a CDMA phone it will not work on GSM and never will since it doesnt even come with a slot to insert a sim card.
yea i know that but the ones that u've seen on every website and videos r not the OFFICIAL EVO i think cuz they didnt even announced the official date but if its CDMA im out of luck and wish for a GSM version of the EVO.

It's 100% CDMA w/no SIM slot. So I guess your out of luck
The big thing about the EVO 4G is the fact that it's a CDMA/Wi-Max. If it had a SIM slot, and you put it on a GSM network like T-Mobile, you wouldn't be able to connect to Sprint's 4G network and lose the one big advantage of this phone. Sure it's got 720p HDMI output and 8MP camera, but other than that and Wi-Max, it's got very similar specs to the HD2.
The other reason could be the fact that they wanted it to run Android, and I have yet to see any CDMA/GSM World Phones running Android natively so they may not have worked out the whole dual mode switching in Android - but I could be wrong about that one.
well.......i guess i have to be patient for something better by HTC on GSM carrier network with ANDROID 2.1.honestly i bought the HD2 and i've flashed custom ROM but still not satisfied at all with WM.i would get me NEXUS ONE but then again better phone will come out by HTC every 3-4 months.as far as 4G its not necessary for me at all.i will patiently wait till end of summer for the better.thanks guys

As they saying goes.."one bird in hand.. is better than two in the bush"
that being said... I live in a WiMax area and have the Overdrive. It is faster than 3G but I can only get 20% signal in areas that I am most in.

So when is this mythical HSPDA+ coming out? WiMax has already been out for over a year where I live, and I've not heard of a single person with WiMax-like speeds on any other carrier. T-Mobile is typically last to the game in that regard, but either way, you guys already have the HD2, which I'd rather have anyways.
WiMax is not certified 4G and will never be. I'm really shocked that Sprint hasn't been called out on this and hasn't had their false adverts of a "4G" network pulled.

why would it have to be "certified 4G?" also, from what I've read from the beginning, is that WiMax and LTE are SO SIMILAR, that it wouldn't cost much for Clear/Sprint to fully convert. The even planned on having a combination of the two services.
methinks you doth protest too much.

wimax and lte use different freqs, converting would not only change the protocol(like software) but the antennas, transponders, receivers and transmitters (hardware)
then all the phones themselves would need new radios (hardware + software) It would be a huge mess, I highly doubt they will convert the technology, hope they just adopt LTE with Wimax and your phone supports both someday. As they already have chipsets that support both technologies at the same time with multiple radios and transceivers. But my money is the conversion of technology will not happen, it will just be integrated into the phones instead of the towers.
Now the wimax/4g thing, wimax has been branded 4g, 4g is a general term...(yes I know it's a stardard and has minimum req's) but the term works for it's purpose; recognition more than a actual "standard". evdo started getting called 3g when the 3g term got popular and was a "feature" and was easier to remember no actual feature was added for them to call it 3g.
The point is the idea gets across, as it is agreed they both generally mean the same thing, you know what it means, they know what it means, and making that kinda correction makes people sound like asses. Much like spelling correctors.
BAM! I knew I read that before.

not everything on you read on the internet is true, but facts are facts.. look
Wimax operates on 2.5Ghz
http://en.wikipedia.org/wiki/WiMAX#Spectrum_allocation
LTE operates on 700Mhz
http://en.wikipedia.org/wiki/3GPP_Long_Term_Evolution#Frequency_bands_and_channel_bandwidths
the two operate on two extremely different frequencies, you can't magically change a phone that is built to operate on one freq to start using one that differently. It's just not physically capable of doing it. No amount of software is going to change that.
That article was written in september 09' sprint has moved forward with wimax, they have made their decision, once they put equipment out in customers hands, they will have to cut some customers off by making drastic changes at this point in the game. To jump back at this point would be insanity. The infrastructure is already being built, and in some cases already built.

Why is that? Radios can transmit on all sorts of frequencies... you have no idea how they designed their antennae or transmitters. If Clear says, themselves, that the technology is 80% identical, then it's fairly believable. I've been hearing that for years, anyhow.
Hell, just look at AT&T, they have 3G on all sorts of bands, and that didn't stop them people from using them. This argument is pointless. Clear could have hybrid modems in store, or possibly their devices can already use the spectrum to reference. All I'm saying is Sprint/Clear aren't really committing false-advertising. Comparing some mythical unicorn that T-Mobile *might* have in a few markets sometime soon, to WiMax, which has been out for quite some time, doesn't make much sense.
For now, it's 4G... the fastest, and I believe they have the right to call it that. It's Sprint's fourth-generation network. For years, the carriers bounced back and forth as to who had the fastest network, and you didn't see anyone renaming their from 3G.

I have no idea how they designed their transmitter? This is more or less true, I don't know the exact specifics of their radios, but I have a really really good idea. I used to fix radios for the army... I have an good general knowledge of radio technology.
I don't have the exact links but I've posted some to chipset makers in this forum. One is for the evo's chipset, and one for for a future phone's chipset. The future one has radios *note plural* built in that are capable of broadcasting on both the 700 and 2.5 frequencies. The EVO's is not capable of the 700mhz only the 2.5ghz (among others 800 & 1900 but not 700)
The reason you can tune civilian band and police radios to multiple frequencies is because of transistors. But you're talking a very small spectrum. A common span is like 1-50Mhz difference. The Bigger the gap the bigger and more elaborate the electronic circuitry is required. Having to tune amplifiers as well as antennas. I'm not going to give a lesson on radio broadcast technology cause, well I'm just not.
For antennas they have to be cut to exact length based off their wavelength to preform optimally. As the frequency increases the length gets shorter but the principal is still there. It has to be more or less exact, the more you deviate the less clear the signal will be with the higher freqs the more exact it needs to be. Fudging a difference that big will not work for a clear and precise digital signal.
SO... while a cell phone radio might change it's freqs slightly depending on open channels, the range is fairly close, a radio that operates on 700mhz might go as high or low as 725 for example but it will not, and I repeat will NOT do a 1800Mhz difference. Hopefully that sheds some light on this subject.
I can't go into how their backend protocol is worked, because I honestly haven't ever messed with it and would only be speculation on my part. So it might be correct, the software might be easily interchangeable, but the hardware is not, and clear/wimax even stated so in that article. They said they had equipment capable of both or options or something. But a change is needed for sure. The evo is sprint's flagship wimax phone, and it is not capable of the freqs lte currently uses.... end of story.
i have a unlocked hd2 using AT&T i know they say it wont get 3g unless i bought the australian version but every once a and a while it will get 3g for 20 sec to a minute or so am i the only one experiencing this
That sucks, I was hoping to be able to move this to AT&T eventually. There's no point if there's no 3G though.
AT&T and T-Mobile uses different 3G bands. There is no way you will ever get AT&T 3G on a T-Mobile 3G phone.
to get a hd2 that can get at&ts 3g you have to buy hd2 t9193 thats an australian phone
OHHH NOOO!
CRAP! This is what I get for not doing my research properly. I have been absolutely HATING T-Mobiles network, I can go anywhere with my Tilt 2 and HD2 and the Tilt 2 ALWAYS has better reception and better G connections. T-Mobile is rolling out this new "Ultra G" but even if the speed hype is true, I seriously doubt that the COVERAGE will improve. And their coverage SUCKS! Ahh, but I love the HD2... Plan was, as others said, to move back to AT&T eventually, using this phone. NOW what do I do. Find an Aussie that wants to Trade?
no one will want to trade i recommend you sell yours craigslist or how ever then jump to eBay buy one from Australia cause if you bid on one of those t9193's that are here in the us expect to pay close to 800 if you buy from Australia you'll spend a little under 700

I too have noticed this. Especially on the northern side of the DC area. I've driven through and each time I get the 3G symbol for a little bit and then it drops out. So you're not crazy or anything else. I'm glad you shared this because I was wondering also.
makes me think that some type for software would enable AT&Ts 3g on the US hd2
I wonder also if they have the 850 mghz one in their supply chain and don't know it or don't care and have released them. I'm heading back the same way again this week, so I'll keep my eyes on my phone. I wish there was a way to tell what chip it is and what bands it will pick up.
They couldn't "just release" or enable cross-band functionality like that without clearing with the FCC first, and that hasn't happened. When the HD2 first received it's license it was certified to exclusively work on the bands specified, and AT&T's were not among those. And, even if you were able to "hack" it to work, you'd likely be violating the law.

I guess but it's not really an apples-to-apples comparison because you don't have to defy the laws of physics to jailbreak an iphone...but you would have to do just that to get the HD2 to work on AT&T's 3G bands.

well if you remember the first iphone jailbreak hats off to GEOHOT was a hardware and software jailbreak. i my search how to make my hd2 get 3g on AT&T i want to know what do you think if i'm to buy a 3g antenna from htc.au and replace that with my 3g antenna what do you think
soooo incredible capable of getting 4g?
no. no hardware for it
That's just wrong. I wont even get update on a new phone for a while. Oh well.
It's not...wrong. 4G requires a new piece of radio hardware to be installed in the phone...besides the fact that Verizon hasn't even lit up the country with LTE yet, let alone 7 months ago when the phone first game out.

lol really?..
Everybody says it is impossible. I say it is but won't happen. "LTE" is not 4G. It is 3.5G, just like sprint does not have 4G, They have 3.5G. If they had true 4G. We would be looking at speeds as fast as out home internet now. LTE runs on a 700mhz band if I am correct. The Radio in both the EVO and Dinc are a qualcomm radio. Which by verizon is set to receive signal at 800mhz and 1900mhz. There is no reason why they can not send out a radio and antenna update to make it also run at 700mhz too. But that is my two cents. this is always what I have thought.
I would like for this to be true.
Can this be true? Please?

well, unless you have something to back up your claim that a software update will enable 4g...excuse me, 3.5g, then your basically talking out your ass. no offense intended, just back up your claims
LTE is actually different from 4G... Look into it and you will see Verizon is claiming that LTE will run at least 3x faster than 4G. Whether they can back up those claims has yet to be seen.

LTE Testing and "G" question
Ok for the 1st thing about radios and software or hardware, as an RF engineer I can say that if the stripline rf sections are capeable of being tuned far enough to run the 700MHZ band, and I will confirm that VZW LTE is in that band as we are running it now, the protocols are different so I do not beleive the chipset will be flashable to run it. They may have indeed looked forward enough to make it so but I have no specific knowledge of it, except that VZW is going to release an LTE version that is in the EVO case but with LTE instead of WI-MAX, good news because front cam and everything. A history lession though is that I have an old HTC PPC5050 in my collection that was an evaluation unit for Sprint back before the 6600 came out and was never accepted and released. This thing had a GPS hump on top of it that really worked when everyone else was AGPS only, and in the spec was EVDO before Sprint even had it. I used it in the first tests of EVDO at ACS in Anchorage and it worked, the first EVDO smart phone and it was never let out, so some strange stuff does happen, I just do not think VZW would have motivation to flash LTE if they could, but just my opinion, could be wrong.
The "G" thing is more company hype and advertising than anything else. LTE is getting 20-35 MBPS with nobody else on it so when it is public, shared, groomed, and throttled who knows but I know it will whip WI-MAX ;-)
It Won't Happen..
LTE Will Require A Sort Of Sim Card...Droid Incredible Has No Sim Card Port. So We Won't Have LTE
You guys make me laugh.
Ill just end up buying a phone that's capable of doing it. Maybe incredible HD.

It will be a few months before there are any LTE capable handsets on the market. Even then, unless you live in one of the handful of cities that will have LTE next year, you'll simply just be using 3G.

Someone on AndroidSPIN mentioned this and I figured it deserved it's own topic because this may be hard evidence and not speculation.
Steven Drzaszcz 1 hour ago
There seems to be credible evidence here that the original Vibrant, at least in theory should support 14.4 : Halfway down the page, it mentions the samsung vibrant using the infineon 5703, which on their site, lists Class 10 as the chip support (14.4 speed)

If the SGS does, in fact, have that chip- it could support 14.4 and be software locked to prevent it from accessing it. Anyone who knows more about hardware wanna take a stab at this? Thanks Steven at AndroidSPIN for bringing these facts out.
that is quite intriguing. Wonder what the "unlock key" is for this thing (if this is true.)
Nice post, I was just mentioning something like this in another thread.
It looks like they tore down a euro I9000 tho, not a T959.
I'm still willing to bet it's the same chip.
Now to find the method they used to cripple it.....
I think they have the same chips.
Interesting, that would be awesome if this was true and we were able to get 4G!
The Vibrant is capable of HSPA, not HSPA+. Basically meaning the Vibrant can use the tmobile 4g network but NOT at the advertised HSPA+ speeds. You will NOT be seeing 14mbs downloads on the carriers network.

How fast have people got their Vibrants up to? Just got my gf a Captivate and it would be awesome if she saw a speed boost whenever AT&T gets off their fat ass and joins the 4G party.

Do you know anything about hspa? The 7.2 hspa uses 16qam the 21 hspa+ uses 64qam. Same technology, same band. Simply faster modulation unless they use duel band in which both techs are supported. Im saying its possible. Not that it does or doesn't but I can debunk the not possible.

AT&T has upgraded almost all of their 3G network to HSPA+ already. The reason AT&T speeds are slower than T-Mobile speeds is the simple fact that they have considerably more customers accessing their network at any given time.

I'm gonna guess the fastest anyone's ever gotten on their Vibrant is 7.2mbps.
Just a guess.
remove your sim and power up the phone and hit (*#2263#) it will take you to a network service menu you want to select all bands and you will be utilizing the 4G network at that point....You may need a New 4G SIM card and or a Rom that Supports the 4G Data...Just my thoughts.

Why haven't they announced a single 4G phone yet? I know AT&T and T-mobile share part of their network, so I'm surprised that I haven't heard anything so far.
My understanding is that the 4G also has to be enabled by T-mobile for your account.

I tried what you said and yes a menu does come up, BUT, the selections are
1 Automatic
2 WCDMA BAND (Which is only GSM 3G)
3 GSM BAND (EDGE/GPRS)
4 COMBI BANDS.
It would seem if the theory is true, then certian software would have to be mod(ROMS) so that it would unlock or reconize the chip as being able to use the 4G data side for T-mobile/ATT. I know all of T-mobiles sim cards are the same regardless if you have a 4G phone or not. If the device/phone is able to pick up the signal it will automaticly, I don't think there is a separate data plan for the 4G(I'll be talking to tech support to verify) But Tmobile is switching to newer sim cards that will work better with there network in every phone regardless if its 4G/3G/or Edge.
i just got off the chat with a rep about the sim card thing
Julian Magana: if i enable 4g threw my plan will i need a new sim card
~Michael C: Welcome to T-Mobile Chat service Julian. My name is Michael and for your reference my rep ID is 13-20364. First, please allow me one moment to review the information you have provided.
Julian Magana: hello
~Michael C: Thank you for your patience. All of the our data plans for Smartphones will support the 4G speeds. There's no need to change your SIM card.
Julian Magana: ive seen several articles out the the vibrant + and the original vibrant are the exact same thing minus the ffc
~Michael C: I can't really say anything until Samsung releases the specifications of the new phone, since we don't have any information on it yet. It's possible that it could be 4G since we have a few 4G devices out, but we can't tell until Samsung releases the information.
Julian Magana: ok and i found this which compares both + and original
Julian Magana: http://www.phonearena.com/phones/compare/Samsung-Vibrant-4G,Samsung-Vibrant/phones/5138,4747
Julian Magana: what do u know about that
~Michael C: I can't verify how accurate the information is because the details haven't been officially announced. According to that link it supports current 4G speeds (21 mbps)
Julian Magana: so if rumors are true, then the original vibrant can fully utilize 4g speeds but samsung has it hardware locked correct?
~Michael C: I haven't seen any cases where a phone was able to go from 3G to 4G speeds because of the firmware, the phone would need to be designed to use the 4G network.
Julian Magana: meaning a 4g antenna correct?
~Michael C: I'm not sure of the exact details, but the hardware needs to be built to use the 4G network. The Vibrant was a 3G phone released before we made any 4G phones, I don't think changing the original Vibrants to 4G would be an option.
Julian Magana: well if thats the case then im sure there will be a 4g antenna mod
Julian Magana: thats all the questions i have thank you for ur help
~Michael C: You're welcome. Thank you for contacting T-Mobile Chat. Have a good day Julian.

yes the chip is capable of 14.4 but is locked for now to 7.2, Some guy from Samsung even comfirmed this as well, infact he confirmed It I believe on January 11th or the 12th when people were talking about the Vibrant 4G.
Very interesting! I'm holding a possible free upgrade to the vibrant 4g in my hand! I'm keeping aneye on this thread!

Just an observation but can the T-Mobile techs on chat get just a little bit of credit for...
1. being fairly knowledgeable about their products
2. doing a pretty good job of not promising something they know they can't deliver
3. being nice enough to put up the sh*t we propeller heads tend to give them via a chat or phone support session?
I know this isn't quite the right thread for it but a good part of the reason I've stuck with T-Mobile all these years is that they have always seemed to do a better job at supporting their products than their competitors...
So, lets give them credit if credit is due to them for doing a good job in the face of the swelling public outcry!
