i have the 4th generation ipod touch. ive always used the charger that it came with, all of the sudden it wont charge and it says "charging is not supported with this accessory" is there anyway i can fix this? i havent updated my ipod or anything, it just randomly started doing this
Have you tried rebooting it? It may seem like an obvious answer, but you'd be surprised at how often it works.
^ as above. Or maybe there is something wrong with your cable. Try a different one? Or a different USB port/wall socket.
