Sim card unsupported?
I bought an iPhone 4S yesterday for at&t and I am stuck on the activation screen. I try to use an at&t sim and it says sim is unsupported on itunes. It is unlocked for any gsm. I put in a tmobile sim and I get service but I cant activate it through iTunes or over wifi. Any help? Its running iOS 6.0.1
iPhone 4S, iOS 6.0.1
