Before I set an appointment at the genius bar, I just wnat to check to see if this is a common thing or not. So far owned ipad for 2 weeks, crashed three times so far(dark screen, spinning wheel, wheel freezes, then returned to lockscreen). The first time, I was opening twitter. Second, entering passcode. Third, playing with gestures, opening and closing apps while bored. Let me know. Is this a common issue? I am a bit hesitant to take to apple store, because the genius at the store that is close to where i live, they ALWAYS find a reason to not help me with the issue. They say stuff like "Oh I cant recreate the issue", "try it for another week and if the problem continues, set up another appointment and we'll replace it for you".
