    Wife ordered an iPhone 4, want to sell her 3GS.

    I have a friend who wants to buy it, but he is on Tmobile, so want to know if we just out in his SIM card, will it work?

    I know it will probably work for calls, but what about data?

    It has to be unlocked for it to be used. Data would be 2g & 3g in some areas
