Verizon S3

Is there a reason Verizon did not get its own forum for the S3 like the other carriers did?

I don't know.... kinda weird.
Guessing it's because the Verizon S3 hasn't been released yet while the others have
Rogers don't have one either .. but everyone saying Rogers and Telus have the same version as Att..
So I'm guessing VZW and Sprint will be the same

It's still currently being discussed and we should know something in the next two days of how it's going to all play out.

[Q] Is At&T Galaxy S4 unlocked?

Hello, I am in USA right now, can I buy Galaxy S4 from AT&T and then unlock it to use in my home country?
Sent from my Galaxy Nexus using xda app-developers app
Nope it ain't unlocked and i am yet to see any working unlocking methods however the carrier may opt to unlock it for a hefty sum ! Also an unlocked version of s4 was spotted on ebay a little while ago

Att or T Mobile?

I have a att s4 i337 and my friend wants to trade me his Black s4 for my white s4. His s4 is from t mobile. Should i trafe him or att is better?

Are they both 16GB? If so, do it.
Tmobiles s4 > Atts s4
Why? Tmobiles isn't bootloader locked and works perfectly fine on att. Just similar unlock (6$ or so on eBay).

After buying an ATT S4 with a locked bootloader (MF3 - should have done more pre-purchase research), I just switched all four lines from my family plan to T-Mobile, after years with ATT contracts. TMobile is paying the ETF's, will cost about 1/2 the monthly ATT cost, and gave me a $165 trade in on my S4. And, now my phone has an unlocked bootloader (went for Nexus 5 at $400 instead of S4 at $640!)! ROM heaven, free at last ...

T-Mobile GS4 FOR ATT

Hey guys,
Had a couple of questions that maybe some of you could answer... I've got an AT&T sgh-1337 and wanted to trade my dad for his T-Mobile GS4... Since MF3 doesn't allow me to have any fun.
Is it a good idea?
Will I still get the same LTE speeds?
Does anyone know if all T-Mobile GS4's are unlockable (bootloader)?
Thanks.

The t-mobile doesn't have a locked bootloader, I would trade...
LTE will be same.

What up with carriers locking bootloaders?

Are us At&t custom ROM users going to have to move on to greener pastures with this Knox bs or will someone unlock the s4, note 3, and s5 (when it comes out) bootloaders at some point? Just curious if anyone has any insight on this, cause if we can't unlock it I'm definitely moving on to another carrier, personally. Or at least I'll buy international unlocked or Google editions in the future. Thanks and f at&t and Knox!

Bootloader being locked has nothing to do with KNOX. And AT&T has already released an official statement a while back that said they plan on locking ALL carrier branded phones in the future.
I understand that they are locked. Now can you actually answer my question on whether or not someone will figure out how to unlock it?

How would someone know that? There have been Bounty threads out for awhile and no luck. If they are still active you can follow them--

They lock them to keep people from hard bricking their devices. If it stinks...buy a Nexus or GPE device
I think we have to wait a while till the s4 becomes old news. Then att will care less about it and there will be less updates and more time for someone to find a crack or leak for the bootloader unlock and the carriers will care less

I think I'll just be done with at&t then probably. It's too bad that companies won't allow you to do whatever you want with YOUR phone. That's why I never got an iPhone! I actually don't mind running stock TW but I don't want to be stuck with it forever. Thanks everyone!

Sad part is until it's paid off it not really your phone. Since they have a warranty for a year to cover issues it only makes sense. Now if they would provide an unlock after that warranty is up and the contract is settled then it would make sense.
Att will never have a unlocked device again, watch and see.....
And these are the reasons I'm going to be moving over to T-Mobile or nexus devices. Just tired of AT&T all together.

Another view:
I will stay with ATT as Verizon is too expensive and TMO in my area has sh**ty reception. ATT has been perfect for me in that area.
Also, I have been a heavy flasher for almost 4 years. The phones now are powerful enough that flashing roms is not that important to me as it once was. If I can get root with Xposed/Gravity Box/3Minit I am good. Plus there are fairly good backup apps now that Nandroiding isn't that critical.
I don't see much more coming my way, after this year, in improvements I am interested in. Something like a Note4 or S5 would be as far as I care to go.
All IMHO of course
:good:
I thought that I read somewhere on a T-Mobile thread that the latest update locked the bootloader on the S4. Was that incorrect?

I'd go to the note 3 if I swapped to T-Mobile. I'm honestly tired of the s4 and the features don't wow me anymore plus the note 3 would be better in spec wise as well.

The i337 bl was always locked but the loki-doki exploit bypassed sig check and allowed us to flash recoveries and kernels. With mf3 they closed that loophole by "blowing the Q-Fuse", whatever that is. Googled it but forgot what I read.
And now you are limited to flashing mostly TW roms <4.4. No custom recoveries/kernels.

I'm not talking about a I337 from AT&T. I was talking about a T-Mobile M919 or do they use the exact same firmware?
