I had an ipod screen that was cracked like a spiderweb...heat related I think, bc of the timing at which the horrible cracking appeared. The LCD had also developed a thumbprint sized spot and the battery was just about useless (at full charge it MIGHT run 40 minutes). Apple quoted me almost the price of replacing one to fix all that and I said fuck that.
So I ordered a new faceplate, a new LCD and a new battery for a total of around 20 dollars from amazon, cracked that thing open with a pair of tweezers, watched a couple of youtube instructional videos, and replaced it all myself. (I should add here that I've never done electronics repair work before, but I figured it couldn't be THAT hard...)
Put it all back together and voila, looks and works like new!
lol at all the sand I had on the inside of that thing....it's a wonder it still functioned at all.
