I bought 2.0 and it downloaded for about 5 minutes then I got an error message that said 'Ipod could not be restored" Now my screen on my ipod is black and it has the apple logo in the middle of it and there is a circle at the bottom of the screen. None of the buttons I press do anything and Itunes does not recognize that an ipod is plugged in. I really don't know what to do!😡
