It used to work but I put it in storage for a year or so and now its broken. Recently I thought I'd get it out to test if I liked fumbling around with a little screen ... much like I would if I buy a smart phone. So, the only thing that comes up is a usb cable pointing to iTunes. It will do nothing else, it's stuck on that screen. I know there is a factory reset, but it will erase everything I had loaded up on there Is there a non destructive way to restore this thing?
