Hi
I have recently purchased a used iPhone 4 from a friend who had it on Orange. I wanted to use it with my O2 account (I currently have an HTC One X on O2). My friend paid Orange to unlock it and 56 days(!) later, they emailed her instructions on how to unlock the phone. This involves sticking a non Orange 3G SIM into it and connecting it to iTunes. Once that is done, they ask you to push the restore button in iTunes. However, the message I am getting starts along the lines of "The SIM car inserted into this iphone does not appear to be supported". Therefore, I cannot push the restore button. Has anyone else ever experienced this? Any help would be greatly appreciated.
