3G IPHONE on tmobile's new 3g network

[AlexiFortuni]

so i know we still dont know much about tmobiles 3g network, but lets say the 3g networks are the same (att and tmobiles) would unlocked tmobile iphones need different sim cards?? i read somewhere that att sim cards are 3g ready .... hmm??

Bottom line: we won't know for sure because we don't know exactly what frequency radios will be in the new iphone. Most bets right now are that it won't support Tmobile USA.
