IOS5 + Ipad2 = Periodic Crashing
I updated my iPad2 to IOS 5 over the weekend, as requested by iTunes when i sync'd on Saturday. Since then, the iPad is periodically quitting and restarting during use. It doesn't seem to be app related as it has occered while using Safari, e-mail, Scrabble, InsideLine, Monster Fantasy Sports HD, and Ebay motors apps so far. I have tried closing all other apps and running one at a time, but it still did the periodic random restart. I tried turning off all of the iCloud syncing options, still no change. The iPad2 was stable under the old OS and never crashed or did this random restart thing. By the way, when I reference restarting, it really restarts, it goes blank, then after a bit, the white apple logo is on the screen, then the unlock screen appears (after some time). On a few occasions, merely sliding the unlock slider caused it to reboot yet again.
For reference it is a 64gb ipad2 with about 20% of the storage memory in use, wifi only. The iPad is not and has not been jailbroken, it is bone stock.
This is really frustrating. Any suggestions?
