when I hit the power button on my ipod, it doesnt turn off the screen like it should. instead it dims the screen and only shows my bottom bar/slider, and a wallpaper that is black fading to a little lighter at the top, and then the black above that where the statusbar is. how do I fix this? I dont want my screen or my battery life ruined! EDIT: got it working! just needed a few hard resets, like most problems ive had lately.
