    Hi guys!

    So I got my AT&T iPhone 4S today. Lo and behold though, that recently AT&T dropped ST as a MVNO over the Bring Your Own Phone program (Or so i've heard. Because No wal-mart anywhere around me stocks the ST AT&T Micro SIMs anymore. And the only ones I can find are on Amazon for about $70+)

    Anyway. Since the iPhone 4S uses the GSM 850, 900, 1800, 1900, and the UMTS/HSDPA/HSUPA 850, 900, 1900, 2100 MHz bands, I was wondering if it would be at all possible to hook my AT&T iPhone up with a ST T-Mobile SIM card, and still have everything working? Because that seems to be the only way I can go.

    ST only clarifies that GSM phones need to run on the 850 and 1900MHz bands to work on their network, so I imagine it will.

    This will only work if your AT&T Iphone is SIM unlocked.

    Well, turns out that Straight Talk and Net10 are the same pre-paid company; ST was just a Wal-Mart branded part of it. Net10 still sells AT&T Micro SIM cards on their site.

    I can factory unlock this iPhone for resale value. But I'll just hop on over to Net10 :)
