I just got an iPhone 4 that I bought on eBay. I put in a new sim card that works on another iPhone 4 but I cant get the ebay phone to activate. The itunes screen will only show the orignal persons phone and asks for ssn and zip. the guy even gave me the info and it still wont activate. Does anyone know a work around??? Spent 4 hours with apple tech support and Att and none of them could get it.
