Tmobile Version has AT&T LTE support, and unlocked bootloader?

So far it looks like the Tmobile S4 has LTE/HSPA+ support for AT&T, and no real signs of a locked bootloader. Anyone else plan on buying that version and unlocking it if the bootloader is in fact unlocked?
Does anyone know of any apps that would test the LTE/HSPA+ bands the phone is capable of? I want to go into a Tmobile and use a test unit to see if I can get service with my LTE AT&T SIM.

Edit: Well, it looks like I'll be getting the Tmobile variant unsubsidized and use it on AT&T. Tmobile will unlock the phone if you pay the total cost up front. I just need to find a replacement back cover to rid myself of the stupid Tmobile logo on the back... lol.

If I had the money to buy the S4 outright for full price, I would just get an i9505.
EDIT: Spoke too soon. The i9505 doesn't support AT&T's LTE bands.

Can you post info on the source? I was also curious about this but i was thinking if we changed the radios like they did in the past that maybe we could get something working?

I put the info in the OP that I have so far; the LTE/3G radios are reported to support all of AT&T's bands. The bootloader, I'm going off of a guess since I don't think that Tmobile could afford to bribe Samsung to lock their bootloaders for them.

HMM, ok thanks for the info so far. I might have to go out and pick one up and test it.

Looks like the T-Mobile version has all the same bands and some extra ones added in. For instance the at&t only has lte bands 4&17. The tmobile version has LTE bands 1,2,4,5,7&17. Will T-Mobile unlock their phones for u??

I'm feeling like a newbie today cause I have my new T-Mobile Galaxy S4 in front of me & still playing with new features after 3 hours.
Tell me how to check to see if bootloader is unlocked and I'll do it.
Also trying to remember where we go to unlock the developer tools. Only remember that it must be clicked 7 times?
Just remembered, Settings.About Device>Build Number <Click Build Number 7 times, back out and Developer options magically appears.
Now i can go into it and toggle USB debugging. Now I only feel 95% newbie.

Has anybody tried their T-Mobile phone on AT&T yet?
If so, I have a couple of questions.
1. Can you use the T-Mobile phone to wireless tether (become a wifi hotspot) on AT&T's network? The AT&T version can be used to tether (with a simple hack). I was just wondering if a different .APK would be needed to do the same with the T-Mobile phone on AT&T's network or if the T-Mobile phone already has an APK installed that works on AT&T's network?
2. I realize an existing AT&T sim card can just simply be placed into the sim unlocked T-Mobile phone for it to work, but how would I go about changing the imei and other phone info that AT&T has in their system about the phone? In other words, would AT&T cause problems with anyone using a T-Mobile phone on their network even if the person paid full price for the phone and it is unlocked? Would it be better to have them change the system information at a store versus over the telephone?
3. It is reported that the T-Mobile phone works fine on AT&T's LTE network, has anyone verified this and does the phone show LTE when on AT&T's LTE network?
Thank you for any replies. Hopefully this information can help people decide if they want to buy the T-Mobile S4 to use on AT&T or not.

You can, for now, use PDAnet for tethering.
As far as changing the phone to appear as "unknown" to AT&T's system, don't do it without a backup of your /efs folder. I don't recommend doing it either because it's not really worth changing things around to hide that you're on a Tmobile phone, because for the most part, they don't care as long as you're paying them your monthly bill. I personally know a friend who has used her unlocked HTC Amaze on AT&T without issue (she was stuck to 2G speeds). The only way for you to have an "unknown" phone on your account is to use an international model phone such as the HTC one or the i9500 (unconfirmed that the i9300/i9500 model is entered into AT&T's system, I only hèard a rumour that AT&T has the IMEI of those phones in its system). My i9100 currently shows up as "unknown" in my bill statement.
I took a screenshot, but I don't have a link of the LTE working conformation (attached). I won't be getting my phone until I am on holiday in New Hampshire so that I can avoid the sales tax on purchasing the Tmobile variant. I would ask my parents to buy it for me, and I send them the money, but they have no technological skills whatsoëver close to asking/knowing what to ask for at the Tmobile store. Sorry guys, lol.

using AT&T phone with T-mobile SIM card

Would it be a problem using the AT&T branded SGH-I337 sim-unlocked phone with the T-Mobile SIM card here in the States?
I was told at T-Mobile store today that the voice calls and SMSs should be no problem, but mobile internet would be a big issue.
I don't know whether it's worth or even possible to reflash the phone with T-Moblie firmware.
The reason being I have 1 bar or signal at home (or even less when it rains), regular phone with international SIM card does not even pick up ATT - T-M only...
They gave me free ATT 3G MicroCell - got the full bar but in the weak areas other party still hears mostly distortion.

no,it be a problem, i bought my GF a T-Mobile unlocked S4 model M919 and she uses it on LTE here in canada all the time. Rogers and ATT have very similar networks so NO, it would def not be a problem

What are the things you need to do? Thanks. Trying to do this now.

It will work regardless. But if you want to make it pick up all of tmobiles bands you need to unlock aws.. I did it yesterday. Worked fine without it but works way better with it... Didn't take long and was easy. Just follow the steps
FYI you Dont need tmobiles firmware. You just need your phones frequency's unlocked so its more compatible to T-Mobile. Att uses 1900 frequency and T-Mobile uses 1700, 1900 and 2200 I believe. Atts phone dont have the other frequencies unlocked without you doing it

AT&T doesn't use AWS, except in very very VERY few areas, and only for LTE. They use 700 MHz. Verizon uses 750 MHz.

But Verizon is starting to activate their AWS spectrum in "major metropolitan areas" but there are conflicting reports in regards to the Verizon variant of the G2 and AWS.
Especially since most recent Verizon LTE phones can access the spectrum yet it hasn't been confirmed for the G2.

Do you understand what AWS is though? It's just 1700/2100 MHz together. AT&T doesn't use it (except as I said in like less than 1% of their LTE areas). AT&T uses 850/1900 MHz for HSPA+ ("4G") and 700 MHz for LTE (which Verizon devices don't do).
AWS is what T-Mobile uses for LTE though, so you'd be able to get T-Mobile's LTE out of the box.

No, it's more than just the modem file. Like you said, just go and buy the AT&T (or T-Mobile) version. The T-Mobile version will work on AT&T fully as well.

I posted before that, yes, a T-Mobile device will fully work on AT&T with LTE and everything. If you don't have LTE on it when you put the SIM in, call up AT&T and tell them to turn on LTE on your account (if you've never had an LTE device on your AT&T account before).

T-Mobile devices are the same as AT&T devices; the only thing different is that they also support T-Mobile's 4G (which uses AWS) where as AT&T devices don't. I promise you it'll work. Just make sure you ask the buyer for a receipt to prove that he paid for the phone in full; you might end up with a device that gets blacklisted because the buyer decides not to pay for the phone/his bill in full.

I don't get why people still think they can just bring a Verizon LTE phone to ATT OR ATT LTE to Sprint or Sprint LTE to Tmobile, etc. It is pretty ridiculous that most people don't understand how cell phones work and never look at the frequencies that are supported on the phone.
About Verizon AWS LTE...Verizon has said that they are only deploying 5,000 AWS LTE towers by the end of this year and willing be adding more sites in 2014. You think 5,000 LTE sites is a lot considering that Verizon's network comprises of 45,000 towers. Let me tell you it isn't considering that is only about 1/9 of the total towers spread out nationwide. You'll be lucky to get a stable LTE connection if you only have LTE BC 4 support considering the shorter range propagation characteristics of AWS spectrum. Anyone thinking of bringing over their Tmobile LTE phones to Verizon better think twice before doing that assuming they will get the same LTE range and coverage as its 700 MHz LTE network.
To me it is always easier to just sell the LTE phone that I am no longer a carrier with and buy the carrier branded LTE phone to avoid all this hassle of unlocking it and having to worry about frequency incompatibilities.

Verizon and att share an aws band. I know about phones, im not dumb. I was just exploring the possibility of it being achieved. If the phones have exactly same hardware across the board, than it means its software related, which in the android world, with alot of trial and error and work, most software issues can be overcome. Thanks for your huge rant though, you should go work for Verizon

[Q] Putting D801(tmous) variant on ATT?

So I was looking over the difference between D800 (ATT) and D801 (TMOUS) and it seems that the reception difference is D800 has an LTE band 5 and the D801 has an 3G band of 1700. Whats the practical difference in reception? Seems like att is starting to grow band 5, and 1700 is tmobile. I travel to some remote areas and I think tmobile works there and att struggles (not sure at least it did 2 years ago), but do like the idea of freely switching between the two without having a tradeoff. will probably start with straight talk for att but will switch to the tmous if i cant get service where i move.
Please share thoughts on the best strategy...

The D801 CM maintainer was out of county apparently and I'm guessing he held off on uploading everything since he's been gone for a couple weeks and didn't want to push something that would be broken for weeks by chance. We'll start seeing a good bit of roms in the coming weeks and by everything moving to KitKat we'll be in as good of shape as any other device since our devices are plenty similar to each other.

LTE on AT&T with D801?
I can't seem to find a clear answer on whether it's possible to get LTE indication and speed on a D801 (TMo) used on AT&T.
Tech Support is giving me the "we can't guarantee data speeds on non-AT&T-branded phones".
This thread seems to say a TMo-branded phone (LG G2 in my case) CAN be provisioned for LTE:
http://forum.xda-developers.com/showthread.php?t=2506590
Most other threads say no, or there's no conclusion in the thread.
Can anyone give me the straight answer and tell me how to go about it? A way to get past the stone-walling AT&T techs?

I have H2O which uses AT&T's network but only HSPA+ and not LTE but the phone sees AT&T's LTE network when searching for networks.
In this thread there is a screenshot of a T-Mobile phone getting LTE indication on the AT&T network.

Along with a lot of confusion about why his phone was working on LTE. As a relative newb to this stuff I couldn't make any sense of it.
Also in that thread was this comment:
T-Mobile devices support ALL AT&T and T-Mobile bands, except LTE Band 5 (used by AT&T in a few rural areas). What's wrong is AT&T turns off LTE for non-AT&T devices. You have to call them up and give them the IMEI # of an AT&T-branded device (even if it's not yours and even if your SIM isn't in it/you don't plan on using it). They don't check after that.

[Q] Claro D801 compatible with T-Mobile LTE?

So I recently bought a fully unlocked D801 G2, though I did not know it is a Claro model from Puerto Rico. I just assumed all D801 models are fully compatible with T-Mobile. Before updating to 4.4, LTE with my T-Mobile SIM was working just fine in 4.2. After updating to 4.4, I am only getting HSPA+. Is this because it is a Claro model? But what would explain LTE working in 4.2 but not 4.4? This is a completely new phone and unrooted. This is my first Android phone, so I am still getting the hang of things and hope I didn't buy the wrong model.

I know that, but what I meant is that despite getting signal I was not getting any functional data (the arrows that should have been there were not).
But I ended up fixing the issue by finding the default T-Mobile ROM somewhere, and flashing it onto the G2 instead of the Claro ROM which obviously blocked T-Mobile bands... I now have my phone running CloudyG3 with LTE working perfectly fine, but thanks for everyone's help.
