Unlocked T-Mobile phone on AT&T 3G?

[sbaker25]

I understand (I think) that T-Mobile uses different bands for its 3G than AT&T. So, my unlocked TP2 doesn't do 3G on AT&T's network.

My question is, can that be changed with a ROM? Are those frequencies embedded in software are hardware? I really like this phone and I'd rather keep using it than sell it and get an AT&T version when it's available (with the AT&T keyboard).

Thanks,
Shane

Unfortunately, can not be changed. It's radio hardware and of course sorftware support. You will need to get a ppc for the at&t for 3g bands...

One of the mods (GSleon3) has said that he can get 3G on his unlocked Fuze on t-mobile in the Raph rom forum, but it only works for a while, and if he soft resets the phone, it basically freezes and then he needs to do a hard reset. It can be done, but not well, I guess. I guess you're trying to go the other way. You may want to look up the thread, there does appear to be some hope (but very little, lol).
