I had Ios 6 beta 4 and I am trying to upgrade to the GM version. I tried restoring it on the computer and it wouldn't let me so I just tried doing it on the phone. That was a bad idea. I'm now stuck on this screen that says device is not registered as a part of the iphone developer program. I am not registered for it and when I plug it into the computer it says the same thing and my device isn't showing up as my normal account so I can't restore from the computer or anywhere. What can I do? I just want to be able to use my phone, this is very frustrating.
