I have an AT&T family plan and have an AT&T sim installed, when I unlocked the iPhone it works, but when I put my GF's Cingular chip in, it says "Incorrect SIM. Insert unlocked and valid SIM to activate iPhone" how can I get it to work? I checked the forum but couldn't find anything so if someone could help it is appreciated. Thanks...
