Has anyone else had this happen. My iPad for the first time since launch dropped to 10% battery, I plugged it in to charge it, before i went to bed. I place it on the stand and noticed it was rebooting. I waited. My wallpapers were the same but the front page icons were default with the message on how to move em, while the rest of the icons were all over the next 6 or 7 pages. I had to spend some time reorganizing, but I never seen this happen before. I was charging and went to open the ABC app to watch something before I went to be. What is also odd, is the device seems a little snappier now. I have turned it off and rebooted it 4 or 5 times before. What causes this?
