HTC Omni, the successor of Universal !

Paul on MoDaCo brings the first info abou the successor of HTC Universal - the HTC Omni !
Read the full article
I'm think support of HSDPA too, but the Samsung processor (same as in TyTN) is too slow for the best PPC Phone ed. device :-(

Sounds good, can't find a single picture yet though, how annoying!!
My O2 contract renewal is in a month, do I delay upgrading and wait for this, or will it not be out *that* soon?

So reading this it sounds like it will be to the Exec as the 2i was to the 2, or am I wrong?
Will it actually be VGA or will we need to hack it again :-(

WRONG!!! Samsung processors yield 30% more performance than Intel. That means, if there is a 300 MHz Samsung, it's every bit as fast as a 390 MHz Intel. 400MHz Samsung = 520MHz Intel. Also it drains less power.

oh sorrry, Yes I'v missed this

Now if it has a 533(+) MHz Samsung S3C2440, GSM-Quad-Band, Bluetooth 2.0, HSDPA, some sort of 3D-accelerator (like the nVidia GoForce) and built-in GPS I will be very happy - and maybe throw in an 1" hard-disk-drive (Seagate has one offering 12 GB now, after all, Windows CE 5.0 supports it, right?) while you're at it.
OK, one can dream, but I have been waiting for such a device for years now - and of course this info just HAD to come in as I was ready to finally get a Universal for a whopping <50 EUR from my provider - but then, I'd be stuck with it for two years, while everybody else gets to play with the (superior?) Omni. They better come out with substantial info on this device soon, before my provider drops the Universal from their portfolio for good.

As long as it's quadband and VGA I'll buy it in a heartbeat... I will never give up the VGA screen on my universal - I use it almost daily for remote management of the servers I manage and I need that VGA screen, but I use Cingular here in the US and the lack of an 850MHz band is a serious annoyance. I can't wait until any quadband VGA device is out... hopefully with EDGE support as well. I'll be keeping my eye on this Omni.

Anyone get hold of any pictures of this wonder device yet?

Why dont they ever listen ???????????? " Popular demand" says an external screen is a necessity not a luxury. Now even though the design is said to be "fluid" after waiting so long an external Lcd wouldnt be asking too much OR perhaps more $$$£££ in the form of Universal 3 is the cause! :?

sorry Brotha, I dropped them for a very similar reason. I actually think that cingular is predominantly 850mhz, but the universal doesn't support 850, it supports, 900, 1800, 1900, and 2100 mhz. I switched to tmobile, who happens to have GREAT 1900 mhz coverage mostly everywhere. As long as you don't live off on a farm somewhere or in a real rural area, tmo should have 1900 coverage in the area. Now with T, I get 3 - 4 bars everywhere I go, with a solid 4 bars here at home. The only other consideration is that US UMTS coverage cannot be 2100mhz atm because the military uses that frequency for its satellites. So you're stuck with GPRS speeds or battery consuming wifi. For a while I just paired and DUN'ed the Exec with my Fathers sprint Apache.

TouchHD U.S Users - your Thoughts Please!

I am alarmed at the following article :
http://www.engadget.com/2009/01/07/atandt-slowing-edge-to-force-customers-to-switch-to-3g/
I know there is still ambiguity about whether it is a hardware limitation or something that can be done in software, but if this holds true.. i may have to give up the best phone I have ever owned.

That doesn't really make sense, considering the fact that where I live, I don't get 3G coverage anyways...

I've seen no such slowing from my HD. I purchased the HD after an experiment with the US version of the Diamond last year. I had used the UK Diamond since it came out in June and then purchased the US version to get the 3G speed. I rarely saw the H or 3G indicator on my US Diamond, I received Edge service in more than 95 percent of the places I travelled during the period of my experiment. I returned the US Diamond to Best Buy and resumed using the UK version until I got my hands on the HD in late November.
The HD works fine for me without 3G. I can use Wifi when I need it.

I agree... 3G coverage is spotty at best in the States and I've had good performance with EDGE for AT&T on my HD... Admittedly I'm usually in a WIFI hotspot at work so EDGE is only for when I'm on the road but still no complaints.

your worry is real. but it won't come true for a long time -- your phone will last till you switch to a new one.
reading the replies below your post, and the original article (which I also read a few days ago). there seems to be some misunderstanding, i will try to explain, and then address your worry. I will use simple terms, although may should foolish (ie. point 1)
- faster the frequency, the faster the battery drains, because the signal oscillates faster. 850 times a second verses 1900 times a second. for those not familiar with signal, just htink of your phone vibrating 850 times a second or 1900 times a second. the latter kills more battery.
- the higher the frequency the less penetration ability it has.
- frequency is freqency, antenna is antenna. an antenna tuned to 850 MHz frequency can transmit 850 MHz signals, simple enough? but the signal may be modulated differently hence the difference between a 2G and 3G 850 band. so you need different hardware to decode and demodulate the two signals, even though the frequency is the same.
- what AT&T's article is saying, is that. they are not going to add extra towers to broadcast 850 3G signals. rather, they are converting 850 2G towers to broadcast 3G 850 signal. This saves them tons of money, because they only need to, for illustration purposes, flip some switches to modulate a 3G signal, instead of purchasing and deploying the towers, since the existing towers are already tuned to 850 MHz.
so yes, when this "fliping switch" operation is done. phones without 850 3G band will only be able to operate on 1900 signals, hence battery drains faster and worse signal indoors.
but back to my first paragraph, judging from AT&T's past records, it would take them a year or two to finish this operation. so .. at least for me. by the time, i will be moving on to a new phone, and i will keep in mind my next phone will have 850 3G chip (or.. if you have learned from my posting, an 850 3G demodulater

Buggy i know you know alot about these types of things (reading your post in the 3g limitation thread) Would you have any thoughts of something and someone that would be able to help us get the 850 3G frequency working?

I am quite impressed actually at the EDGE speeds I do receive. I don't do much of YouTube and other things that require an intense of amount of data when I do use the internet. Google Maps and Live Search works just fine on EDGE. If I need to browse the internet I just use Opera Mini which works awesome on the HD I might add.
The only complaint I have about this device is that it's not 3G. If the great minds on XDA or somewhere else some how figure out to get 3G then that's even better.
I can't wait to see what new devices HTC launches this year. I hear up to 10 new devices. Heck we might even see a HTC Touch HD Pro with the necessary 3G 850/1900 frequency.

3g
I love my touch HD Edge works great 3G is a big hype

I am surprised with the edge speeds on this phone, way quicker than the Omnia, but.... Get for example an iphone 3G (not trying to make a comparison or a phone war as i am not even a fan of it just the first 3g phone that pops up) and go on to the same website and at same time and you will notice a huge difference in my opinion. The HD uses the same exact radio off of the touch diamond American version so i think it should be possible to enable it.

Is X1a phased out?

I have noticed that X1a has disappeared from US site in favor of X1 (900Mhz UMTS X1 model):
http://www.sonyericsson.com/cws/products/mobilephones/specifications/x1?lc=en&cc=us
I remember distinctly it used to be the X1a up there as it still is for S. America site, e.g. Argentina:
http://www.sonyericsson.com/cws/products/mobilephones/overview/x1a?lc=es&cc=ar
same change (as in US) holds true for Australian site - used to be X1a
What's going on? Certainly, I wouldn't think that whole nations changed their frequency plans in favor of Qualcomm
In this case to whom is the recent R2A North American ROM upgrade addressed? Was the initial issue of the X1a for the US a limited issue on first come first served basis?

Hmm
I'm no expert, but I wouldn't call the phasing out of the X1a a "first come first serve" I'd call it more of a "this device sucked, lets replace it with the one that works".

What The! The X1 and the X1a are exactly the same device except one supports 900Mhz UTMS and the other 850Mhz.
As far as the Australia website showing the X1, this makes sense as they are probably about to release this version here (We only got the X1a version last December). But the X1a is still listed on the website.

Heh I'm just ranting for the heck of it lol. But as an Electronic Engineer it makes no sense to me to have the 850MHz when you have a 900MHz, because the 900MHz can easily be set to work at 850MHz in software.
That being said, my little rant was based on things I have read on other forums about a lot of problems (network and quality related) being most prominent in the X1a (850MHz) devices. That being said, It's quite possible that it was just the specific production batch that was making those 850s at the time. It's also possible that maybe the guys that own X1as (Americans) are more likely to complain, or simply that a significant number more of tham have been sold, because of geography and customer base.
Don't take anything I say to seriously, I sure as heck don't

That's cool lol. I didn't know you could set a 900MHz to work at 850MHz via software. I would have thought if they could do that they would, instead of having to produce a seperate batch for each band. Certainly would decrease production costs.
I genuinely think a lot of complaints are from those people who didn't really understand what they were buying. Either they had never encounted Windows Mobile before and expected it to work like any other Sony Ericsson, or they had inflated expectations of what Sony could do with the software. I'm not saying there haven't been some production issues though.
I see Windows Mobile a lot like Linux desktop OS. Out of the box it's a bit underwhelming; but take the time to play around with settings and programs and customise it to your liking, it can be very powerful and unique.

Yep

Yep, totally agree. Back to the 850/900 I think the problem here is entirely political rather than anything Engineering wise. America didn't conform to the international standard set for GSM as did not a few other countries and so they make the 850 devices for you guys. However, a quad band GSM which is the X1i, should work in America just fine because they support 850 and 900 (like I said, the 900MHz can easily be made to support 850 in software)
About the WinMo/Linux Desktop thing, I agree again, although not entirely (a Linux desktop OS has never been underwhelming for me) because I always know what to expect, and that's that I make it run how I want, the beauty is, it's designed that way.
WinMo however, was never designed to be user customised, and considering SE have done close to nothing with it over the WinMo PDA I sold 3 years ago because it was so horrific nearly gave me a heart attack at my new "investment" but I think the fact that it was made by HTC has left a lot of room for improvement because a lot of their in-house customisations have been ported and made useful here.
Right now I'm happy with my Xperia except for the one flaw I have just today addressed with Send/Receive over Wifi while sleeping not being possible, which is a huuuuge blow for me.

I thought that the UMTS bands were hardware based...
Both phones are quad band GSM... but neither is quad band UMTS.
I'm trying to remember where I saw this, but I think there was a chip in the phone that allowed the UMTS bands so a simple software change wouldn't fix this. So the X1i wouldn't work on 3G in the US or on NextG in Australia.

Yes, I think alias_neo is talking about a different frequency set
The 850/900 frequencies he's talking about are for GSM - this has never been the issue with the X1i/X1a imbroglio
It's the UMTS 850Mhz fequency that the X1i is hardware-crippled against
An X1 model with 900/2100Mhz bands for UMTS (such as listed in the 1st post) is another variation again. Some countries use the UMTS 900Mhz frequency for their regions, but it is not widespread. We need further confusion like a hole in the head !!

Ahh, well, I have lost track of where this is going now, and since I havn't slept in 2 days (it's now 6:30am on the 3rd day) any point I had is probably flawed. i think my point was that the "Hardware" crippling is probably more of a low level software crippling and could infact be rectified (only by the chip manufacturer) using the same hardware. But again, I think my point was that the reason they have this difference is political and because some countries refused to stick with the international standards.

No, you misunderstand me, by software I mean low level machine code, "burned" into the chip by the manufacturer and not changeable. Only he manufacturer of the chip can do this at the point of manufacture.
But of course I could be entirely wrong, I make this assmption based on the fact that I often work with "programmable systems on a chip" (ASICs/FPGAs etc).
It's also quite possible the frequency setting circuitry IS infact made the good old fashioned way of laying out the silicon in a set circuit design.

1) "some countries" include Canada, US, South Americas, Australia, South Africa.
The UMTS 850Mhz frequency is used in the regional (less populated) areas to cover the distances involved with a longer wavelength. Such areas need less bandwidth too, because of the lower population densities
Politics plays no part here, thank goodness. it's just straight physics.
2) the "international standard" for cities is 1900/2100Mhz. All the cities I know that have UMTS broadcasting use these frequencies, including cities in the above listed countries
The concept of larger, less-populated areas is probably not easy for city-dwellers to grasp, but the "international standard" for such areas is UMTS 850Mhz. The only "odd-ball" aspect here is that city-dwellers don't understand this, I think.

Nup- there are many, many 900MHz regional deployments.
Australia is unique in the sense that it has both a 900MHz and a 850MHz regional deployment. Lots and lots of stupid redundancy. Oh well.

I can't disagree with that - there's marketing politics in that redundancy (not hard to guess ), but either 850 or 900 serves OK for the regions. The physics is essentially the same for either frequency, of course.
However, the 900Mhz in Aus has a very limited deployment, primarily because Optus et al do not want to service the less-populated areas (not sufficient profit). They've been paying lip-service for lo!, these many years.
The 850 frequency became a problem with the Qualcomm-Broadcomm Court issue and this turned up after the 850Mhz deployments
I agree ... oh well !!
The way I see it turning out is that Telstra, who operates the 850Mhz with easily the largest areal coverage, will gradually "corner" the retail market on UMTS 850Mhz devices in Aus and proceed to charge unbelievably high $$ amounts for these. It's already difficult to find 850Mhz devices at any significant discount to their prices. And yes, that's marketing politics ... but the physics dictates the parameters.

In which case, there is no reason 850MHz couldn't be the standard as I assume that even here in the UK our less populated areas would equally require less bandwidth and could live with the extra coverage, of course you would then have to count the rest of Europe and Asia who also use this band. A lot of Europe has wide open spaces just as much as they have cities, there are few countries that don't fit into both categories.
The question, I guess, is how much extra bandwidth are we really getting from those extra 50MHz, or extra coverage from the 50MHz less that determines that there can't just be one standard everywhere in the world.
Of course that's before you get into the fact that some countries may have already allocated the band to something else, making it impossible. (As with USA and the 1700(?)MHz band.

X1a and X1i differ in hardware:
i.e. different UMTS power amps for 850Mhz and 900Mhz

Hehe, like I explained before, and as the poster above has just shown. They are infact made by entirely different manufacturers for different bands, and by software I meant the code actually "burned" into the chips by the manufacturer, ad only by them I meant it could be done, not by some software you install/run on the device.
Anyway, in this case I was incorrect and as I stated earlier, it is possible (which is in fact the case here) that they would use the good old fashioned way of making the chips by actually designing the individual circuits into the silicon directly rather than using programmable chips.
This of course would be because of how critical obtaining an exact frequency is and designing dedicated chips like this ensures that.
In conclusion, you might as well disregard everything I have said on the subject. Either way, it would have made no difference to us the end user, just that the manufacturer could easily (if they wanted) made the cips run either speed.

Nexus One has hardware to work on AT&T 3G

I was looking at the Nexus One teardown here. http://www.ifixit.com/Teardown/Nexus-One/1654/2
Interesting to note that the RTR6285 RF transceiver does indeed support Band 5 UMTS, which I think is AT&T, according to a cached press release here. http://74.125.153.132/search?q=cach...l+RTR6285+umts+bands&cd=1&hl=en&ct=clnk&gl=us
Note it says...
North American triple-band UMTS (bands 2, 4, 5)
Japanese triple-band UMTS (bands 1, 6, 9)
European, Chinese and rest-of-world triple-band UMTS (bands 1, 3, 8)
Also... the power amplifier SKY77336, according to this document... http://docs.google.com/viewer?url=http://www.skyworksinc.com/uploads/documents/200780E.pdf
Does support the GSM850 band. Isn't that AT&T?
So what is really preventing the Nexus One from running on AT&T? Did they just not "bother" to certify it with the FCC because T-Mobile is their launch partner?
This could mean then the radio software, or some other configuration option in the firmware simply has AT&T 3G disabled.
I'll let you guys debate this, but I can't see any hardware reason why this phone couldn't work on AT&T 3G, with proper software/hacking of course.
-James

Actually the real question is, why didn't they certify with the FCC for AT&T 3G? My only idea is that T-Mobile was the launch partner, but the hardware can do AT&T 3G technically, it's just not certified and enabled.
No reason they couldn't certify and enable it later.
And I have to say, I would have no trouble going to T-Mobile, but in Salt Lake City, AT&T coverage is far superior and so are the 3G speed tests. There are many locations my T-Mobile friends can't get make calls to save their life. I hear T-Mobile is much better in other cities.
-James

Doesn't AT&T use both 850 and 1900 for 3G? Does this phone have 1900?

You've already answered your own question here, GSM is not UMTS.
I'm in the smae boat btw, Telstra in Aus use 850UMTS and I know how painful it can be to have 2G access in most places.

Well technically UMTS is a GSM standard, could be the same thing. Same frequencies certainly.

I was just checking the brochure for the http://www.rfmw.com/data/BRO254-08B.pdf
No where does it make mention of UMTS, like say... T-Mobile's AWS... but it does specifically have the correct frequencies listed for both T-Mobile AWS and AT&T 3G.
I'm going to make the assumption that this indicates it works with UMTS is both bands since it doesn't mention UMTS specifically at all, yet it does work on T-Mobile AWS.

James I love you man! tell me there's a way to "jailbreak" this thing.... what kind of people do we need? someone has to be willing to help with this. Oh why oh why am i only a MBA.... I need a tech degree of some kind!
I don't think it has to do with the FCC. Though we are all in love with the nexus one... remember that google and apple are nearly HALF of the same executive board. They don't want to compete with the golden goose that keeps thier stock portfolio's up that much.
We just need to find out how to activate/change which airwaves this thing is listening too and THEN we will have the first truely unlocked machine!

subscribing to this thread for an outcome.

I've been doing more reading and it seems this isn't the first phone with hardware disabled. I haven't found anything yet on if anyone has made the change yet :+\

Well, maybe. The Blackstone has a hardware limitation for the US 3G frequencies. There have been phones in the past that had software limitations that were overcome with a hack. So if the Nexus has the hardware capabilities to do ATT 3G frequencies there is a good chance that someone will figure out how to unlock it.

uh...wow. Yeah, I'll be watching this thread.

Which phones? Do you have any links we can read so we can start looking for similar solutions?

I found this link to the Diamond on XDA which they supposedly change to 3g at&t but I have read the whole thing it's long.

I'm still looking for answers! I'm just not smart enough to "create" the answer. I have hope that a future rom will help us but not for a while. For now I'll keep researching.
P.S. my phone comes tommorrow!!!!!!!!11 I'm so excited!!!!!!!!!!!111111

The radio chip supports all the UMTS bands it but unfortunately the UMTS power amplifiers (eg. http://www.skyworksinc.com/Product.aspx?ProductID=597) are NOT in the chip. Like the G1 it probably only has amplifiers for 900/1700/2100.
The quadband power amplifier only supports GPRS/EDGE: http://www.skyworksinc.com/Product.aspx?ProductID=437
Looking at the chip diagram here (http://s2.guide-images.ifixit.com/igi/ZhrRALhPFhWyLGKC.large) the two chips next to the SKY77191 look awfully like power amplifiers as well.. if so, conveniently for 900/2100

Don't get me wrong, I wish this worked on AT&T (points at logo). Guess I'm EDGE-only until my contract expires.
Just wish all carriers would have stuck to one standard

whoever helps figure this out will definitely be getting some donations from me!! i have att and no purpose of buying a N1 without 3g...

Is this a lie, GSM in EVO?

I assume this is a lie. I see no mention in the teardown of GSM capable chips. Saw a video on youtube where some girl had been fed some misinformation that the EVO could run on T-Mobile.
As I understand it the only CDMA phones that work on GSM are verizons World Phone Blackberries. If anyone can weigh in on this, let me know.

while the snapdragon DSP can do GSM, the phone doesn't have the electronics (antenna and transceiver) for it
http://www.qualcomm.com/products_services/chipsets/snapdragon.html
The QSD8x50 platform consists of the QSD8250™ which supports GSM, GPRS, EDGE, HSPA networks while the QSD8650™ supports CDMA2000 1X, 1xEV-DORel 0/A/B, GSM, GPRS, EDGE and HSPA networks. Both chipsets include:
1 GHz CPU
600MHz DSP

Support for Windows Mobile®, Android, and a number of Linux®-based operating systems
Qualcomm’s hybrid mode alternative solution

The htc evo can roam on gsm networks but it wont ever be able to work on the network fully with a gsm provider do to not having sim card slot. Unless the phone was completely remade to accommodate one then it wouldnt work.
Some sprint phones have had sim card slots for international use, but the HTC Evo does not.

I think he may be talking more about the auto CDMA fix thing. I personally think it's crap, but whatever people think might help their battery.
I just watched that youtube video and all I can say is wow, that chick is retarded!

I am pretty sure that hyfeno site is just a SPAM farm. It also has similar boilerplate "guides" to unlocking an iPhone 4 with an unlock code (no), the Motorola i1 (no, it's iDEN), and who knows what else.
