Do I have to downgrade from iOS 7 Beta in order to get iOS 7 today? I downloaded the iOS 7 Beta about a week ago and now I'm worried I'll have to downgrade in order to install iOS 7 that's being released today. Anyone have any insight? If I have to downgrade, what's the easiest way?
You will have to download the GM seed from the Developer Portal to move off the Beta. This will once again be a complete clean and restore so make sure your backups are up to date before starting.

Barring any last minute showstoppers the GM build will be the released version.
