would it sync up with T-Mobile's 4G network?

i dont think it will give you 4G or 3G (at least based on the info from the phonearena webpage) but i have high hopes the rumored pentaband might change this (at least on 3G)
don't know how at&t will manage their 3G (all I've heard its gonna use LTE) if so T-mobile has no LTE yet so its not gonna work on '4G' but will have to wait and see

I am not 100% sure about this but it should work on the tmobile network.
AT&T right now is planning to have both LTE and HSPA+ as 4G and eventually going to just do LTE but as of now it will have both.
Atrix 4G is supposed to be HSPA+ device so theoretically it should work on T-Mobile's network and take full advantage of its 4G network....

You will NOT get anthing faster than Edge because of AT&T an T-Mobile having different UMTS bands.

as Kevin said, AT&T phones & T-mobiles phones have two different UMTS sets which control the 3g/4g bandwidth...For all AT&T phones, they are all missing the key UMTS1700 (or AWS) which this is the downlink for T-mobile.
so if u put the t-mo sim on your artix 4G all you can see is the big "E" on top of the notification bar.

good to know. but does anyone know how the UMTS is implemented on phones. does it have to do anything with phone software or hardware?

it's strictly hardware, which is tuned to only send and recieve on certain bands. It's kind of like getting an AM only radio (remember those?) to receive FM, or an AM/FM to receive shortwave
