Does anyone else seem to follow this pattern - mine will be fine for 2-3 days, then I'll get several lock ups in a day, then it will be fine for while. Strange it doesn't happen on a more regular basis. I've tried to figure out what I'm doing when it happens and if there are any patterns, but I can't come up with nothing. I just go to turn my iPhone on and it won't come on. So I go the Home/Power route.
