In case anyone wondered what was insie an Ipod, I took mine apart to replace the battery. First you pry the case apart as shown below: Then you pull the back apart, and fold the hard drive out (blue). the battery is the black thing on the top right of the main body. Mine has a Toshiba hard drive in it.. I think they all have Toshiba's The blue stuff is some sort of rubber damping pad, and has a thin metal plate for some reason.. Then you replace the battery, put the drive back on top, and snap it back together.... It's a tight fit, but I guess that's why it doesn't rattle and stuff. So there you go... exciting huh?
