ey ey, go to the apple store!! they got one in almost all of the big malls nowadays.
they'll check up on it, look for problems, and fix it.. if they can't, they'll give you a FREE replacement! you dont even need your original receipt or any proof that you purchased it. i went with my cousin cause his ipod wouldn't turn on AT ALL. they replaced it for him on the spot!! exaaact same ipod.
