Please help me. My Ipad 2 is stuck on the screen with the circle that spins as if it is loading or getting ready to turn off. I think it might have something to do with that I tried to send some pictures earlier but they didn't seem to send. I can check my email on my computer but my Ipad 2 is just stuck. I tried pushing both the main button and the small one on top. I tried holding either one of them down. I tried holidng both of them down. I have also tried to connect my Ipad to my computer but I keep getting: iTunes could not connect to this iPhone because an unknown error occurred. What's going on? Does anyone know how to fix it?
