At home in the UK, BT home zone, iPad original, iOS5 with all apps hopefully updated, and suddenly crash. App(s) unexpectedly quit, I'm back at the home screen level. Usually the app reopens where last I was reading. This morning with SkyGrid though, I was out in the cold and had to step my bck to the last article I was reading. This happensnwith other apps as well: games, apps with a web connection and apps without. Any suggestions for where to start looking or testing for a culpable culprit?
