I have a regular iPad and the problem is that when i am playing a game, looking at Safari, watching a video, or anything else, the screen goes black for a second and goes back to the homepage. I have found out that this is because if something loads for too long, it shuts off. NOTE: my iPad is jailbroken and if i take it to the apple store to be repaired, i will lose all off my apps. WHAT SHOULD I DO?
