Actually to me the t-mobile galaxy s2 looks clearer and more vivid, for example the picture with the boat and bridge looks clearer on t-mobile version and the red on the boat pops out more to me than the at&t version. Just my opinion though.

Yes it will, I have a att gs2 and works fine. Btw the att version of the Samsung gs2 running exynos cortex a9 beats Tmo’s Qualcomms version, of course both run on the ARM-7 architecture. And both beat the Apples iDont 3-4s as it is a Samsung ARM7 processor underclocked to 800MHZ! Why?. I run the At&t ver. rooted,running Cyanogen 7 on Tmo.

Sadly no, there’s no software fix since it’s a hardware problem. :( Glad to help!

Ah! so no software fix around this, huh?
Thank you for the clear explanation.

Unlocked AT&T phones will work on T-Mobile for voice because the two carriers generally use the same GSM frequencies for voice. But for high speed data, they use different frequencies. Without 1700 MHz support in the phone, you’ll be stuck on EDGE speeds with a T-Mobile SIM. People who buy unlocked iPhones — or buy an AT&T iPhone and then unlock or jailbreak it — have the same experience: voice is fine, but data is EDGE only because of no 1700 MHz support.

Haven’t gotten back to it so I don’t know about the exact frequencies–but it must have 1700, bc/ I am able to make calls from it on Tmobile. Also, data works, with “E” (which I understand is EDGE) on statusbar.
Question is– why not 4G?

For an unlocked AT&T phone to work on T-Mobile’s mobile broadband network, the phone must support the 1700 MHz frequency. You can check on the box to see if the phone does. Unfortunately, if you bought the phone from AT&T, it’s highly unlikely this frequency is supported. In the case of the Galaxy S II, the model sold overseas — in Europe, for example — would work on T-Mobile.
