I have a working 64 GB 4th gen iPod Touch in black. I had to replace the screen and it works perfectly (the screen) but upon reassembly, I apparently didn't get the volume up button seated correctly or something, so it's not working at the moment. I am considering fixing it, but if you know anything about disassembling these @#%#@ 4th Gen iPods, you'll know what a monumental pain in the ass it is.
So... I am seeing if there's any interest in someone buying it as-is. Make me an offer I can't refuse and it's yours with the understanding that it's a used unit with some scratches on the back and some minor scratches on the front, bottom where I got the spatula in there to pry apart. Other than the button issue, it works perfectly. It's likely and easy fix if you have the right tool and patience, but I'm sick of IOS products.
