Anyone getting the T-Mobile version tomorrow? With CDMA not SIM capable, and AT&T version still up in the air, I think I'm probably going to get one tomorrow!
I've got question regarding T-Mobile's werid 3G band tho. I think Samsung listed T-Mobile's version as AWS 1700/2100. I know 1700 is weird, but is that AWS 2100 same as the 2100 band that the rest of the world use? Sorry it's my first 3G T-mobile device, and looking on wiki or google is just kinda vague
2100MHz is the band used all across Europe as well as large parts of Asia.
So, yes, the T-Mobile one should give you 3G capability in other parts of the world, though if it's locked that may open up other issues.

I had a TMo US G1, and it worked fine on 3G when I returned to the UK. The converse was not true of my TMo UK G2 (HTC Hero), which would only get Edge in the US because it did not support both bands of AWS (1700/2100).
So, I see no reason why a TMo US shouldn't work pretty much everywhere else in the world where 2100 3G is ubiquitous.

Cool thanks, i guess that AWS threw me off. I thought there were a regular 2100, and then T-Mobile's AWS 2100

Actually you're a bit off. Tmo's 3G runs on AWS 1700/2100 band which is not the same 2100 *frequency* as the rest of the world. Tmo uses 1700 for downloads and 2100 for uploads, so both bands (aws/band IV) are needed.
Now Europe (and rest of GSM world) use straight 2100 band for 3G but the exact frequency is not the same as Tmo's.
Basically a Tmo Galaxy Tab will only get you EDGE outside of the US. An ATT Galaxy Tab will get you 3G in the US and the rest of the world (as long as it's sim unlocked, ofcourse).

No, the T-mobile phones give you also 3G in Europe. All AWS chipsets do both Band I (2100) and Band IV (AWS 1700/2100).
I thought the galaxy tab is quad band, so you can simply swap your sim card with another european carrier and it should work on thier frequency
Am I wrong?

You're right for 2G, not for 3G
So getting the unlock code for tmobile device and putting AT&T sim card will not give me 3g connectivity (using AT&T network)?

No, because it doesn't support the 850 or 1900 MHz bands.

One could say the same to you.
This is a link to T-Mobile US's support forum, in which someone has had it confirmed from T-Mobile themselves that all devices designed for their network have to be fully compatible with the 2100MHz band, meaning they will give you 3G capabilities in Europe.
Your previous post in which you claim that the 2100MHz band that T-Mobile use is not the same as the 2100MHz band the rest of the world uses is nothing short of ridiculous.
If the band T-Mobile used was different to the one used in the rest of the world, it would not be described as 2100MHz.

Sorry, but as I already said earlier in this thread, my T-Mobile US G1, which is an AWS device, worked perfectly well in the UK with full 3G. Similarly, I know of people who bought TMo Nexus Ones in the US, and these all worked fine in the UK.
That's not to say there isn't some subtle difference which not all chipsets can cater for, but it is certainly true that many TMo US handsets will give 3G capabilities in Europe.

The normal UMTS 2100 is called "Band I" and t-mobile's AWS is called "Band IV":
http://en.wikipedia.org/wiki/UMTS_frequency_bands
The AWS 3G module has already 2100MHz support, so there is no additional hardware necessary to support Band I as well. Theoretically it could be disabled, of course, but then T-mobile wouldn't be able to charge you an arm and a leg if you were to roam outside of the US
I am planning to buy MT4G, unlock it and use it on another carrier with compatible frequencies of course. Will I be still able to get updates using for example a wifi connection? or should I download updates manually? Is there something that I will lose when I use the phone on another carrier ?
I don't know if you mean overseas or in any place other than the U.S. but the only "compatible" carrier for this phone besides T-Mobile is AT&T. The reason why compatible is in quotes is because yes the phone would function and make calls on that network, but you will lose 3G and HSPA+ service as AT&T's equivalents operate on a different and incompatible spectrum.
I would also assume that you would not receive OTA updates either.

Overseas, on a network that is compatible with regard to GSM/ UMTS frequencies. So the only way to get updates is to download them from forums like this one?

I don't know for absolute certain, but I'm 95% sure you wouldn't recieve OTA since it goes out over the network your phone is connected to.
You can usually snag the update from here, but unfortunately, a lot of people didn't run aLogcat to log the download and get the link. Including myself, though I'm trying now with my second device.

Another question, does anyone know if this device works on UMTS band I 2100 ( 2100/1900)? I really can't make up my mind because it's not clear on T mobile website. It says UMTS 1700/2100/AWS and this looks like it's referring only to UMTS IV

The phone is compatible with almost every gsm band the specs are:
GSM 850 / 900 / 1800 / 1900
HSDPA/HSUPA 900 / 1700 / 2100
In the US most carriers are using GSM 850/1900 and 3G 1700/2100 you will only get OTA from T-mobile in the US if you are using their cellphone service or you can hope and wait for the update to show up here on XDA in the forum.
http://www.worldtimezone.com/gsm.html
In Israel where I am, and England, France and Germany etc. the bands are
2G 900/1800 and 3G 2100
so you should have no problem using 3G or even 3g+ "4G" on this phone if your cell provider offers it. But it may require an advanced sim card or signing up for a special data service.
Dont get confused by the various terms (UMTS EDGE HSPA etc.) a phone that is guad-gsm and tri-3G will run the data services just fine but T-mobile will tell you we dont guarantee the data capabilities outside of our network... because they dont want lawsuits

Actually I am a telecom engineer so I know about the terms. You didn't get my question about the bands. Look here for example support.t-mobile.com/doc/tm24233.xml?&A2L.SERVICE=FeatureSummary
The listed Bands: 1 (2100) and 4 (AWS 1700/2100)
and that clearly shows that G2 supports 2 UMTS bands , 1 and 4
1 is 2100 paired with 1900 ( EU)
4 that is used by T mobile in the US.
So I am confused because on this page mytouch.t-mobile.com/mytouch-4g-features#/specs-and-manualsthey listed the bands like this
Bands 1700/2100/AWS that's why it's not clear for me if MT4G supports UMTS I or not.
This is the official reply from HTC when asked:
Dear ....,
I understand that you would like to know if your T-mobile Mytouch 4G device can use the 2100 MHZ band over in Europe for 3G. I do apologize your device is not compatible with the 2100 MHZ back over in Europe for 3G service. I do apologize for all the inconvenience that this may cause you.
To send a reply to this message or let me know I have successfully answered your question log in to our ContactUs site using your email address and your ticket number .....
Sincerely,

AWS is the data delivery method used only by Tmo in the US. So the 4G service may not work outside the US but according to the phone specs it states that it supports UMTS and GPRS/EDGE so it should support 3G UMTS/HSPA/HSPA+ and gprs/edge for 2G everywhere. Ill test my HD (from England) when I get to new york in a day or so and see if I can get proper 3G speeds.
Todays smartphones are designed to be used worldwide with full service as much as possible.
AWS is just another name of UMTS band IV. This is the only UMTS band the MT4G supports, so you'll be able to use it for 3G on carriers that use this band. You can see the list of bands and operators that use them here:
http://en.wikipedia.org/wiki/UMTS_frequency_bands
In short, outside of the US, Canada, and Chile you're out of luck for 3G. You'd be able to use 2G fine though.

Frequency bands differ for different technologies on the same phone. For example there are 2 versions of Nexus one one for ATT and one for T mobile although they work on GSM level because the support both GSM bands on T mobile and ATT but not the UMTS bands on both networks. UMTS and GSM frequencies are not necessarily the same for each network and most probably they won't be the same. In my country we licensed 3G services ( UMTS) on 2100 band or UMTS 1 . GSM on 900 and 1800 only.
Can someone provide me with the FCC id from the back of the phone ?
I tired to search for it on the web but I don't think what I found was the correct one.
Update
I went to T-mobile store today, the guy was helpful and he printed out the official full technical specifications for the device that he pulled out and here what I got:
3G/UMTS Bands
Band I / UMTS2100 Yes
Band II / 1900 No
Band IV 1700/2100/AWS Yes
Band V/850 No
Band VII/ 900 No
The page was titled " Enablers" and listed specs for GSM and UMTS bands with their features. So I think this ends it for me, it does support both bands I and IV.

I got the update by only using my friend's t-mobile sim card, I think I got it via wifi since he doesn't have data plan.

Sent from my HTC Glacier using XDA App
I created this thread because there seems to be some confusion as to the differences between the T-Mobile, Euro, and (soon to arrive) AT&T branded versions of the Galaxy Tab. I'm sure at some point enough information will exist for a proper XDA wiki entry, but for now, we need a thread for each variant with specs, and where possible, hack/flash options, including phone and data connections.
So this will be the US AT&T thread, where we can get the facts straight for those who wish to use AT&T as their carrier with a Galaxy Tab.
THIS THREAD IS FOR US AT&T GSM ONLY, DISCUSSIONS ABOUT CDMA (SPRINT, VERIZON, ETC) SHOULD BE IN ANOTHER THREAD!
Other carrier-specific threads:
US Tmobile Galaxy Tab flashed to make phone calls (currently phone works only, no 3G data)
(I would suggest to moderators that other non-AT&T and CDMA-related posts be removed or moved to a more appropriate thread.)
Alright, for starters, let me post the US AT&T frequency information, so that n00bs can be up to speed.
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/WCDMA/HSPA 3G
1900 MHz UMTS/WCDMA/HSPA 3G
This should be helpful when we discuss the Galaxy Tab specs. I will be re-editing this post as new information comes in.
[future verified information can be placed here]
[reserved for FAQ]
[reserved for links as needed]
Actually, the SGH-I987 version that AT&T is getting has already launched. In Canada. On two carriers.
The Bell version has two model numbers on the back, the GT-P1000M (firmware is different, and presumably less crippled than what AT&T will release, hello sideloading), and the FCC model number of SGH-I987 on the back cover, so the internals are identical to the AT&T unit.
And you missed a few bands, any Galaxy Tab with a SIM card will work on 2100 UMTS as well as 900 and 2100 GSM/GPRS/EDGE.
AT&T should be releasing their branded version of the Galaxy Tab on the 21st (just a few days from this posting). If I understand right (this is where the value of this thread will come into play), the specs for the T-Mobile version are different in terms of the 3G radio frequencies.
IF this is true, then it would mean that if you plan to use AT&T as your US carrier:
You must run an AT&T branded Galaxy Tab
You must run a Euro-spec Galaxy Tab*
*specific procedure for this to work is unverified at this time
Price
At this time, the price for an AT&T branded Galaxy Tab will be $650 from AT&T. It will have two pay as you go plans--$14.99 for 30 days and up to 250MB of storage or $25 for 30 days of up to 2GB. This is similar to how they currently handle the iPad plans.
HOWEVER, as many people here on XDA-devs know, it has always been possible to take a GSM SIM and move from phone to phone, and provided that the frequencies are compatible, the services should carry over and the device change remains largely in the control of the owner. Of course, they can detect the IMEI at the carrier, but in most cases they are not blocking IMEI's. If your device has the right radios and frequencies, it should work. In the past, this has been the case with most devices.
So the question is: Does the Euro-spec Galaxy Tab have the same frequencies as the AT&T branded Galaxy Tab? It should, considering that the specs for the Euro version seem to reflect the same frequencies that AT&T uses.
In theory, getting the software right on the Euro-spec Galaxy Tab should be a matter of flashing a working cooked ROM to enable phone and 3G connectivity.
As of the time of this post, one or two people have managed to get a Galaxy Tab phone service working with AT&T, although I am unsure about 3G.
Again, the purpose of this thread is to clear up these questions, and keep it focused on getting a fully-functional Galaxy Tab on the AT&T carrier. Meaning both phone and 3G working as normal with any other device.
I can confirm that the European Tab works fine on at&t with full 3G and Voice dialing.
It is model GT-P1000
FCC ID: A3LGTP1000
I have been using it for the past few weeks and it seems to support all the required frequencies. It has operated in every mode including (G)PRS, (E)DGE, (3G) and (H)SPA
Stupid question then. Doesn't Canadian Rogers use the same frequencies as AT&T?
They sell Galaxy Tab too right? Does their Galaxy Tab have voice call capability?
I am interested in buying Galaxy Tab that could do 3G on AT&T and can make voice calls so I could use it as my phone ;-)

The FCC docs actually say that the GT-P1000L, N, T models do support 850GSM and 850WCDMA(3G):
Type the device's FCC ID info in, (A3L is the manufacturer code for Samsung). Look at the documents in the 824.20 (GSM "850") and 826.40 (WCDMA "850") lower frequency ranges.
The actual test report docs list GT-P1000L and GT-P1000N and a clarification doc from Samsung says the GT-P1000T model is just a renamed L one.
This is great, it's exactly why I wanted to start this thread. SO, one person at least has a Euro-spec (GT-P1000) machine wortking with voice and 3G data on a US AT&T network.
Someone needs to post specs on the GT-P1000. Because right now, it would seem that the P1000 is the best bet for those who want to use FULL functionality on a US AT&T network.
My personal motivation for this thread is to get solid information on what model Galaxy Tab will have full US AT&T functionality (voice and good 3G data connect), and HOW to achieve that (choosing the right Galaxy Tab and flashing the right ROM). Once this is nailed down, I'll buy one. I just need to know which to buy and what to do to it.

Not FULLY working on at&t's 3g network. The 850 band for 3g is still missing and 850 is their primary 3g band and it's slowly replacing the 1900 3g band. The reason they changed was because the 850 3g band can cut thru walls better and give you a better 3g signal. I remember when my area had only 1900. My 3g sucked. Very spotty unless I was outside. I instantly noticed when the 850 upgrade took place. Solid 3g even in the darkest areas of my basement @ work. There will be an unlocked 850/1900 3g band version on the tab but it looks like it was pushed off until early 2011. Probably because they knew they would never sell any of the current north american models with the 850/1900 3g bands (bell, rogers & at&t) For what it's worth, you can pre-order that version here:

Who said at&t's primary 3G is 850Mhz?
That is just false information.
Their primary is actually 1900Mhz and they are beefing it up with new 850Mhz towers, not instead of current 1900Mhz existing in infrastructure.
Places who only recently got 3G service might be on 850Mhz but all those who got 3G up until 2 years ago are all 1900Mhz with the addition of 850Mhz.

Places who only recently got 3G service might be on 850Mhz but all those who got 3G up until 2 years ago are all 1900Mhz with the addition of 850Mhz.

I need to find the artical that says they are slowly changing over the entire 3g network to the 850 band. Stay tuned.

Yea this article and all the others stating the same are copying the same wrong source.
At&t never said they will be replacing 1900mhz with 850mhz...they said they will be ADDING towers and expending their network on 850mhz.
Here in the sf bay area the netwrok is mainly 1900mhz but they are ADDING new 850mhz towers so now we get mixed frequencies in places where signal was bad. They are certainly not removing 1900mhz towers.

This thread encapsulates my concerns exactly. I want to use my tab as a phone, and am on ATT, so will wait to see how to best implement this agenda before purchasing anything. I have a couple of concerns:
1) I think that the Galaxy Tab forum should be split amongst various carriers, since future roms and such will likely be device specific.
2) Now that more information is coming out with regards to the Nexus s and Galaxy 2, I am wondering whether I should hold out. I do want a large screen, but the development community/google support for the next Nexus phone is hard to pass up... maybe I will buy both!
Regarding splitting up the forums, I don't think that's a good idea. We tried it for the Galaxy S models and it is something of a clusterfuck, and not as much knowledge is being shared IMHO.

Hi, Just making sure this phone's 3G bands wouldn't work in W. Europe's 3G 2100 bands. Can anyone confirm? AWS is 1700/2100, which I think is upload/download. AFAIK, you would need the phone to do both upload and download in the 2100 region.
This phone works perfectly fine in europe on 3g.

What makes you say that? Not that I know for sure either way, but I've just seen answers going in either direction. Some say yes, some no.
Here's what I know:
Most of W. Europe uses 3G 2100 (perhaps a little 900?).
This phone has bands listed as 1700/AWS/2100.
This phone uses Band IV (T-Mobile) which uses both 1700 and 2100 (one for upload and one for download I think).
When the phone is listed as "1700/AWS/2100", does that mean it will do both AWS *and* 1700 upload/download *and* 2100 upload/download? If so, then I'm golden. But, I think this phone only does AWS, meaning that one of the bands is dedicated to one data direction only, i.e. one upload and the other download. So, I'm inclined to believe it wouldn't work on 3G in Europe.
It DOES WORK in Europe!
The phone DOES work in Europe. I used it in Norway in December, France and Portugal in January.
The thing is be very careful no to roam data or it is going to cost you a fortune!!!
If you must roam data, take a look at http://xcomglobal.com/. I used their MiFI and simply loved it!
Hope this helps,

Thanks for the reply, but did you see the H icon then, and not just the E icon while in Europe? I realize that EDGE/GPRS would work just fine for data, but 3G is still in question. Even HTC says this phone, which is equipped only with AWS (Band IV), will not work in Europe for 3G data. I'm moving to Europe soon, and I'd just as soon sell it here before I leave. Thanks...
WHat I remember is seeing an R icon to warn me about the roaming. I turn the data off almost immediately so I did not pay much attention to it. I am not back in Europe until the first week in March. I guess by then you will know the answer...
In Europe ... data not working w/ Euro SIM card
I'm in Germany with an unlocked MT4G and, while the calling feature works, the data/internet package does not. Per the carrier here (Tchibo/O2), they use the 1800 band which to my knowledge IS supported by the device.
Any ideas of why this isn't working would be appreciated ... of course more appreciated would be any ideas for a solution.
Cheers,
The phone works fine with AWS and 2100 bands.
AWS is 1700 MHz band.
The device ONLY supports AWS and 2100. It doesn't support 1800 (which doesn't even exist) or 1900 or any other bands.
This phone is quad band for voice and GPRS/EDGE data - meaning 800, 1900 for N. America and 900, 1800 for Europe. It does not support the 2100 3G band as found in Europe. 3G is only supported over the AWS band in N. America, which is *both* 1700 and 2100 simultaneously.
EDIT: It appears that the specs on this phone are somewhat ambiguous. The phone supports "1700/2100/AWS". It's not clear whether the phone supports BOTH Band I (Europe 2100) and Band IV (N. America 1700/2100). There are very sporadic reports that 3G does indeed work in Europe, and hence, Band I. There are other reports to the contrary. It could be that one group is right and one is wrong, and it could also be that there are multiple batches.

Please set your facts straight / upgrade your knowledge.
AWS is using frequencies in 1700-ish and 2100-ish MHz range.
But:
2100 MHz is a separate band, found in Europe, as well as in most of the world.
It's supported by this phone, regardless of AWS.
I'm using it RIGHT NOW.
And it happens to be fully functional.
When phone specs refer to frequency, they actually refer to an operating band name.
MT4G technical specs state that it supports 1700 and 2100 bands - which are IV and I, respectively.
Thus, it works in Europe, using band I.
And I'm only referring to UMTS bands, not GSM.

Wikipedia isn't so great for supporting evidence. Also doesn't explain why the manufacturer lists the 3G specs as "1700/2100/AWS". The AWS is both ambiguous and redundant if the above were true.

Yes, edited the post. My problem - sometimes the urge to make sure I'm not writing bullstuff occurs after I actually write some
I'll explain the sporadic reports: at least in part of Europe, the coverage is 900/2100 bands and not only 2100 band. In these cases, phones like Nexus One would work, but Mytouch 4G wouldn't. There is another Wikipedia link, list of UMTS carriers with their bandwidth, and you can see which countries are "affected". I remember for sure that France is.
Very few people are credible sources for reports.
First Google result for "Mytouch 4G specs":
http://mytouch.t-mobile.com/mytouch-3g-slide-phone-specifications
UMTS: Yes; Bands: 1700/2100
I don't see any mention of AWS and 1700 in the same place as 2 different bands. And I don't believe that specs should be taken from other sites, that aren't hosting official data. They're definitely not so great for supporting evidence
The phone is 100% working with 2100 band.
Fair enough. Although, it states directly on the box ----> "1700/AWS/2100". Therein lies the ambiguity and/or redundancy.
hi,
would 3G work in the UK with this phone? O2 in Uk uses 2100 W-CDMA so would it work?
Does anyone have it in the UK?
sorry if this is a stupid question.

I use O2 in Ireland with my mt4g when I'm over there with no problems, however my O2 plan is pay as you go with no data so I cant comment on the data there.
I bought a one month PAYG data-only plan while in Sweden (Telia).
I was averaging 3-4mb downloads in areas where I got 3G reception (reception at my in-law's summer house, on the other hand, is a different matter).
I am going over to europe soon, i plan on just turning on wifi and starbucks hope all over faster than 3G
any more helpful insights anyone?
I believe you've got your answer.
The phone works with 2100 band, so you'll have 3G.

not until t-mobile has completed refarming its 1900 frequency to HSPA+ ...at least for the international and AT&T models. im not sure about the Sprint version.
I heard that the Sprint variant of the S3 has a sim slot since its an international phone. All you have to do is root and unlock it and it should work on T-Mobile 4G.

That's not an accurate statement but it makes the point—non-T-Mobile GS3s won't work on T-Mobile's 3G/4G until they redeploy from 1700 to 1900 MHz.
T-Mobile hasn't put out a time table. AFAIK parts of downtown San Francisco (around the Moscone Center), parts of San Diego, and parts of Birmingham, Alabama (i.e. relatively nowhere) are the only places TMO has this configuration deployed.
That's not exactly true parts of Bellevue and Seattle Washington have been reformed too so I'm sure there's more areas

Look up t mobile 1900 mhz refarming. Thats ur best shot. Other than that right now signs are pointing to no hardware support for t mobiles currnt hspa bands. Basically, cross your fingers that tmobile changes to your frequency in your area with this phone. Tmobiles doin cuz they want to steal awayviphine users so they do have incentive. We'll be on that train too tho.

i'm a bit confused here.. maybe you, r3a1ist or someone can help. i called tmo and they said that the samsung galaxy s3 works on their 1700 - 2100 while at&t has 850 - 1900.
i'm really confused because on the tmo website, the specs for the SGS3 says that it works on the following bands:
tmo:
850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band V (850)
i got 4 questions:
1) what frequencies does the tmo version work on.
2) what are the frequencies that at&t uses for its SGS3.
3) what frequency does tmo use for its 4G (internet) network.
4) when LTE comes out next yr on tmo, will samsung release a new line of SGS3 specifically for tmo to work on its LTE?

Never, probably… I don't have a source (you can Google it) but T-Mobile does not have enough spectrum in NYC to do much shuffling.

The Sprint model apparently does not work. The AT&T may work later this year depending on your area. Are you asking whether you want to make a $500+ bet that it will? That's up to you—I wouldn't.

1) It works on the frequencies you posted. Let's rewrite that:
GSM/EDGE (aka 2G): 850, 900, 1800, 1900 Mhz
UMTS/HSPA+ (aka 3G/4G): 850, 1700 (aka AWS), 1900 MHz
Is it less confusing now?
2) AT&T uses 850 Mhz and 1900 MHz for their HSPA+ service.
3) TMO as of July 2012 uses 1700 MHz for most their HSPA+ service. T-Mobile will support HSPA+ on 1900 MHz in some parts of the USA by the end of the year. Very few areas (T-Mobile has only officially disclosed a tower near the Moscone Center, in San Francisco) do so now. Concrete details are sparse and nonspecific.
4) Next year is a long time—the SGS3 will be old by then, and the Galaxy Note 2 or SGS4 will have been announced. Nobody can predict the future. But, looking at the past, TMO released a new "4G" version of the Vibrant, so it's also likely they release new "LTE" versions of their phones.

one last question.. do you think that if i got the tmo version of the SGS3 and when LTE is released that the phone will no longer use HSPA? when LTE comes out, will the phone no longer use fast internet?

Yeah… that's a complicated question whose answer I don't yet understand myself.
TMO is doing their 1900 MHz refarming to free up 1700 MHz for use w/ LTE. Stuff I'm wondering:
What happens to older 3G/4G devices that don't support 1900 MHz? Do they lose their 3G/4G Internet? Note: the GS3 supports 1900 MHz, and does not have this problem.
How is TMO going to deploy in spectrum crunched areas (like NYC)? They don't have enough spectrum to move everyone over to 1900 MHz—does this mean 1700 MHz HSPA+ will be cut off when they bring 1700 MHz LTE online? Your non-LTE GS3 might lose 3G/4G Internet in this situation—but I doubt TMO would do this to anyone with a phone still in contract.
All in all, make your purchasing situation on the situation today. The next new thing is always around the corner.

But LTE is a gsm technology, currently sprints/Verizons phone (Verizon razr maxx works on international/att networks after a recent update) is a hybrid, but they have weird lte frequencies, I've read that all US carriers will have incompatible freqs, but qualcom is building a chip that does them all plus European ones.

It's simple, T mobile phone works on At&t HSPA but not LTE. At&t phone works on its own HSPA and LTE but not T moble 1700 HSPA. We've been trying to see if we can make it work on t mobiles 1700 hspa band, no luck yet. To make matters more uncertain. T mobile says they're refarming their 2g/edge spectrum to work on At&t's 1900 HSPA band. The At&t phone out of the box would be able to pick up this 1900 HSPA t mobile refarm. Although reports of this actually occuring are sporadic and they also fired the CEO who's plan it is a couple weeks ago. LoL. If you get that, that's the complete break down. So here you go:
T mobile phone - Supports both T mobile and At&t HSPA 4g speeds, no LTE of any kind.
At&t phone- Supports At&t LTE and HSPA only right now, t mobile HSPA "may" be available for it's antenna's in the future.
