iPod 4th Generation or Photo Battery
This will easily break, resulting in snapped pins. Will cause right speaker to not function if you don't solder them back on. I don't know how to prevent this from happening, I did just as described in step #21. I even went in from the side as shown in the photo, but probably should have gone in from opposite (RH side in photo) as that's where the pins are.
Awesome - thanx!!!
