Hello, I'm a registered Apple Developer and registered my iPhone's UDID with the Provisioning Portal... yet, when I updated to iOS 6 yesterday, it says that it couldn't activate because it wasn't registered with dev account. So i left it alone over night to see if servers would work tomorrow...(today) It doesn't. Now, I downloaded the IPSW from Apple for iOS 5.1 and tried to restore back to that by putting iPhone in DFU mode then Option-Restoring to the 5.1 IPSW....but it says that my iPhone is not eligible. My hosts file is fine, and I don't block the gs servers.... What should I do now?!
