My ipad 2 keeps doing the same thing, the apple customer care told me to restore to factory settings after a backup and then reactivate. I restored to original settings and now it won't activate. I keep getting an error message saying "cannot activate ipad at this time." It all started when my Ipad kept sending a message that stated "your ipad cannot make cellular calls" which is odd, bc it doesn't make calls.....
then the switching on and off started---
I'm at a complete loss....HELP!
