    I was wondering if there were any differences between the networks that I could get on using a tmobile 9900 vs an at&t 9900 ie gsm, edge, 3g etc . I just unlocked a tmobile 9900 to use it on at&t and I don't know if I've been able to get on at&t's 3g network .. hmm

    thanks for the help!

    EDGE will work but not 3G.

    In my past experience with an unlocked Bold 9000 from AT&T used on a T-Mo account. I saw full EDGE but no 3G due to the antennas being configured differently. I'd imagine it's probably the same way going from T-Mo to AT&T. Especially since the merger acquisition isn't complete.

    Just a thought...
