iphone activation server cannot be reached
About 15 seconds later, it transitions to a 'Could not activate iPhone' page: Your iPhone could not be activated because the activation server is temporarily unavailable. Try connecting your iPhone to iTunes to activate it, or try again in a couple of minutes. If this problem persists, contact Apple Support at apple.com/support. My iPhone 5 that has been running iOS 7 since beta 1 suddenly wants to be activated. When locked, it shows me my wallpaper.
