When I move the arrow across to operate phone it freezes then reboots.. why?
When I move the arrow to operate my iPhone its freezes for a minute, then is shuts itself down then reboots. Why? It happened once a day for the last 3 days and now it has happened 5 times today. I have 10GB available on phone so its not a storage issue. Any help would be greatful as im 3 months out of warranty.
Thanks
iPhone 4, iOS 5.1.1
