I had zero issues upgrading, not even restoring, from the iOS 7 developer builds to the final release. Just download it from Dev Center, option/shift-click on Update in iTunes and feed it the IPSW.

Granted Apple's way of forcing the upgrade here is painful but it's more than possible to upgrade without issues and without bricking your device.

The problem is that Apple did not give us the ability to do OTA update, then they suddenly with no prior notification they decided to deactivate the developers devices, then the forced us to put the device in the recovery mode to restore it!
