Something happened to my iPad today, and I was wondering if anybody else has experienced it too. I was browsing the MacRumors site's front page, when suddenly the iPad would stop responding, the page did not fully refresh. After about 20 seconds later, the iPad restarted in Recovery mode by itself. - I didn't feel the iPad overheated. - My iPad has latest iOS 4.2.x firmware and has never been Jailbreaked. - There's a chance the ipad may have been running short of RAM if any previous apps didn't release it to the system after closing (I was testing and then saving/deleting some newly downloaded apps about an hour earlier than this event). With a little struggle, I was able to get it out of recovery using Tiny Umbrella. It was a savior as I have not backed up my iPad in over 2 weeks. And after being spared from a major data loss, I did a full backup. My concern is whether this was an unusual glitch that may never happen again, or if this is a sign of a serious fault or an early sign of a serious failure. If this is supposed to happen? If it is, it would raise a concern for those of us who rely 100% on the iPad when traveling or working outside their office.
