Has anyone else had a problem with their home screen application apparently crashing, leaving you unable to use your phone until it is reset? This has appeared to me before, but it wasn't much of a problem until it crashed while I was sleeping and so my alarm that I had set on it was never executed and I missed work. I'm just wondering if this is a common problem that I'm is with the newest iOS rather than the phone itself. Is there a way to prevent this from happening again? Any help would be appreciated.
