Switching Ports with other iPod
I have a chance to get another Ipod Nano; same generation and size. How hard would it be to switch things up? My Ipod has a damaged port, but works great otherwise. The other one I may be getting is from Ebay and apparently everything works fine, but they can not guarantee the battery function or the other has a cracked screen. So depending on the Ipod I get, what would you suggest doing in this case?
