I see an ipod touch for sale for $70 with the following description: Ipod (2nd generation). The screen is cracked and the back has normal wear scratches. Here is why I am selling it, everything was working fine untill i tryed to update it to the new Os4. The new operating system update that apple set out. It completely wiped out my ipod and the only screen i keep getting is the usb connection and the itunes icon. i dont know what to do with it. Would anyone know if this would be an easy fix or not? I'm trying to find a used one for my kids and wondered about buying this or not. Thank you.
