I have had this ipad for 8 months now, and the last month and a half it hasn't worked. This started 2 months ago when I was on it, and it blacked out and put a spinning white wheel in front. When I charged it with my iphone's adapter (because the ipad's one broke) then it worked again perfectly. Another night when I was trying to use it, it did the same thing again, but then it blacked out and spinned for hours, without even opening. It spins even after we charge it, or during then when it looses all of its battery it stops. Why is it that? How can I open it again? I have many things there that I need? Please, help.
