20 - 40 分钟
The ipod ended up having a faulty headphone jack. It would only play out of one ear.
It wen't pretty well, the toughest part was cracking the metal panel off, but after that it was smooth sailing. It took me about 40 minutes in total to open change out the jack and snap it back shut.
The photos weren't too clear initially for the opening the ipod.
I actually found opening the ipod from the side to be an easier start. Locate the locking pin on either the left or right side of the ipod start closest to the bottom/Click wheel. Then work your way up.
