    Hey guys,

    I purchased 3 iphone 4Ss, and one of them's SIM card failed today for some unknown reason. I was wondering how can I go about putting the SIM card I kept from selling my old iPhone 4 and changing the # to the one for the iPhone 4S? I'm with AT&T.

    Or, do I have to do what the Att rep said and go to the store tomorrow?
