iMessage
All of a sudden out of the blue the iMessage stopped working, I was unable to receive or send to anyone that I have always iMessaged. I have gone to Messages to ensure iMessage is on (shut it off and back on), ensured I have the most recent upgrade (iOS 7.0.6) and it is telling me "Could not sign in. Please check your network connections and try again".
There is nothing wrong with the network connection, nothing has been changed and I am accessing the wifi withour issue. I have tried shutting the wifi off and using the 3G, but I get the same message. I've shut the phone off and back on and it still will not work. Please help or i am going out to get an iHammer!
iPhone 4, iOS 7.0.6
