Wife's second Nano went out and she went to the Apple store and stood in line for two hours. They were selling the Ipad. She replaced the last Nano at full price and told them she just wanted to have battery replaced. They said she could get a umber and wait for three more hours or come back. She decided to come home.Is there a black market battery for these or can you send them away instead of getting raped for 150.00 for a new battery or buying a new nano. If you do replace battery will it remove your songs.
