If your phone bricked up tonight with an "Activation Error" because you were still on the iOS 7 beta 7.0 instead of 7.0.2, then do this:
- Download the 7.0.2 IPSW for your device (For all Canadian carriers, Model A1428 from https://developer.apple.com/devcenter/ios/index.action)
- Connect your device in iTunes.
- Do an Option-Update.
- Select your downloaded IPSW from Step 1
- Your device will update to 7.0.2.
Lots of talk about this in the Apple Developer Forums too. Glad I wasn't the only one scratching my head.
