Well.... I have the same problem. My iPad keeps crashing. I have NO apps running in the background, everything is closed. I tethered to iTunes and did a restore as if the iPad was brand new. It gave me back my bare basics, and I started over fresh. Then, I went into the app store, and reloaded all the apps one by one, instead of reloading the saved restore. I thought this would remedy the problem, but it has not. It's mostly when I am using Safari, Facebook, or iTunes when the crash occurs. This all seemed to have started after the very last update from iTunes running iOS 5.1.1. This is on a 1st gen iPad. Any other sage suggestions as to what to do next? It's making me crazy!
