I'm not new to iPads, but mine just updated without my permission. Now I'm having all kinds of problems. First how do I delete icons? I searched and everybody says press and hold till they wiggle. Then hit the x. But mine wiggle and there are no x's. Sometimes my screen stays on and runs the battery down. (It is set to sleep in 2 minutes) I had no problems till this update. I don't understand why it updated by itself. Every time it asked, I said no.
