iOS 7 Beta 3 random de-activation

My friend and I both upgraded with registered UDIDs at the same time when the first beta came out and have been able to upgrade without any trouble ever since as it should be. He called me about ten minutes ago telling me his phone suddenly appeared on the activation screen and prompts him to put his Apple ID and password. When he does he gets a message saying that the Apple Servers are temporarily out of service. When he plugs to activate from iTunes it says he can't because he has find my iPhone turned to on. Is DFU Mode the next step? any help would be appreciated, thanks in advance

 

well I didn't know if the issue was related to Apple's server being down having stumbled upon this old thread on the apple help boards

I guess my friend will have to wait and see... certainly his phone being randomly deactivated doesn't have anything to do with apples servers being down
