My ipod screen is stuck. It is solid white and if i press it, i can hear the calculator as if i was using it. I was using the calculator when I pushed the home button to go back and nothing happened. If i pushed the button twice, however, it would pop up with the music dialog. I tried to reset it by holding the sleep button, but the screen just went white. If I press either button, it just turns the screen on or off. Even plugging it into itunes does nothing.
