After a pretty serious amount of searching, I still haven't been able to find a straightforward explanation of what works on which Note 2 on which network as far as 3G/4G service goes. (There was only one that came close, and it still didn't seem to actually be complete.) While the consensus seems to be that the T-Mo phone is the most flexible, what I've been able to cobble together is that the answer is much closer to "depends on what you want to use it for." (Duh, right?) So here's what I understand so far -- please feel free to correct me if I have any of this wrong, and I'll update (or if you think carriers/devices should be added to the list, comment with sources and I'll add on the info):

----

T-Mo T889 (stock unlocked): up to 42 MBps DC-HSPA+ on T-Mobile network (1900MHz); up to HSPA on AT&T network (trying to verify)
AT&T i317 (stock, unlocked): LTE on 700MHz on AT&T network (and future AWS when AT&T gets around to deploying); EDGE on T-Mobile network

T889 with T-Mo LTE unlock (est. Spring 2013): may possibly also enable LTE on AT&T network.

T889 with flashed AT&T radio (or NV partition edit): unknown -- no success to date. Hypothesized that it may enable LTE on AT&T network.
i317 with flashed T889 radio (or NV partition edit): loses AT&T LTE capability; gains HSPA+ (non-DC) on T-Mobile network (DC yet to be verified?)
No idea as to what would happen if/when an i317 can be flashed with a post-Spring 2013 T-Mo radio.

----

So the conclusions I seem to draw from this are:
If you want guaranteed highest speeds out of either service today, and some possibility of T-Mo LTE support in the future, get the AT&T phone and get used to playing around with radio swaps.
If you want the guaranteed highest speed out of T-Mo in a few months (and now, obviously), and some possibility of getting the highest speed out of AT&T (aka LTE) whenever xda-developers' ingenuity figures it out, get the T-Mo phone.

How does this sound to you guys?

Short answer, AT&T Note 2 can get full speed HSPA+ on T-Mobile and LTE on AT&T... I currently have it that way... You need to activate AWS bands on NV partition... I also have the T889 and the T889 can do the same... Remember what I have been telling since day 1... They are both the same phone... Just with different signals pre activated by their respective carriers...

Your search was not too serious, lol

As I understand it the note 2 is the first phone to have all the different model have the same physical design and the software is very close to the same as well. I beleive that there are two internatinal ones the gsm and lte. All the us versions are based off the lte one so they are all very similar. I think we even have a few roms in the dev section now that are based off sprints rom. I could be wrong though. I was a little confused at first because usually on tmo our phone would be based off the gsm interntinal but not this time.
I gotta say I am really happy with samsung. And I am impressed with what they have accomplished with this phone and the sgs3. They told the carriers to go to hell and did it their way this time. I think they were able to do it because android is like 60% of the worlds cell phone market and samsung is like 75% of android sales. I am sure the numbers are off but I remember reading about that last year. Sorry to go off topic a little bit.

You've done this with the T889? Sounded like you haven't yet from the linked thread.

Keep us up to date on exact steps and success here in the T mobile forum section please.

What steps ? It's for the AT&T version......use the search feature dude.

Uh, that's his point. And mine, for that matter. AT&T only so far - meaning my OP is currently correct. Nobody has done it on T-Mo (at least that has reported it here). "Hardware is the same," yeah, we all know that, but we also know the software isn't, so it's a matter of what we've actually tried and succeeded with and have confirmation of.

When somebody actually reports a success with T-Mo they can confirm, I'll update.

Sorry, poor assumption on your part. :) I found that. Did you read past the first post? First post says DC works (which was an edit, apparently yesterday) but post 3 says it only indicates DC, no actual speed bump to DC or 42 speeds. Lots of failures on that thread too. So I listed what worked for the OP. If you'd like to confirm dual-5MHz operation (which you didn't explicitly when you posted your success in that post), maybe some screenshots of the speed change if you have them, that should be fine and I'll edit.

Plain and easy... Follow sjravi's post... Restore T889 NV backup to I317 or viceversa in your case... And voila! LTE enabled on T889...


OP Updated... Even easier...

Right, like I said, as soon as someone's actually done it successfully I'll update.

I can add the NV method to the radio method, I suppose, since both seem to work on AT&T.

Posts like yours aren't much better than trolling. What did it add to the conversation? Search for what?

If you'd actually searched and read the numerous threads across both the i317 and T889 forums, including both the General and Q&A sections, like I have, you'd see multiple claims of it works, or it doesn't work, and varying methods described with people saying they work and don't work. TEKHD has bounced back and forth multiple times on this, along with a few others.

I was just asking for clarification that this was done on a T889 or not, since TEKHD said in the post I was replying to that it does, but in the thread he linked he said it didn't.

This is a T889 forum, isn't it? What do the users of the T889 care about an i317 hack unless the same hack will work for us?

LTE on T889 Phone

Searched and found conflicting repoerts. Is it possible to get the LTE working on AT&T using the Tmobile T889 model of the note 2?

I hope you guys can help me, I'm frustrated already, I bought an AT&T SAMSUNG-SGH-I317 and also purchased an unlock code, phone was working just fine with 4g on AT&T ( Tested ) but after unlocking I just don't get service when I use a T Mobile or Simple Mobile SIM.

On the About Phone -> Status I do get "Network: T-Mobile/Simple Mobile" ( Depending on the SIM I use ), but I don't even get EDGE, I cant make calls, I get the annoying emergency calls only, its making me crazy. Is there a way to fix this issue?

( I already added the APN settings, but im sure I don't need that to make calls, or get EDGE, I don't know what else to do to fix this ).

Thanks

HELP so confused =[

I have a TMobile Note 2 N-7100, its now unlocked to use with my AT&T sim. it shows that i have 4G speeds, i am searching the threads and getting mixed messages about enabling LTE. i came across this http://forum.xda-developers.com/showthread.php?t=2068041 but it was non-specific about working on At&t, even though if it works which i have not yet confirmed is there another way to enable it without running the risk of "bricking" my phone?

Im confused... do you have a T-mobile Note 2? or a N7100? I beleieve the N7100 is the AWS International one, the Tmobile Note 2 is T889... or you could have an N7100 ROM flashed on a T889 (which existed in order to get 4.1.2 before the Tmo release).

    It is thought so, but no one's done it yet.

    Ah ok... so i just got ATT today and am using it on my tmobile note 2. DO I need to do anything at all to be getting the best speeds or is it getting the fastest it can right now until someone gets LTE working>?

    I just tested mine the other day. I have an unlocked T-Mobile N2 running clean rom ace 4.7 T-mobile option, and perseus kernel. I put my wifes At&t sim in and applied the att lte apn settings and my note 2 picked up att lte just fine with the T-Mobile radio.
