So I bought the 2.4 GhZ white one after being told these would be unavailable tomorrow when the new ones are shipped to the shop. I was also told that I could return the white one when the new ones are available. Does anybody know if I can return it when open and used and what time frame I have to do this in? Also, I have taken the barcodes from the box in order to get my iPod Nano Student rebate. Is it ok to return it in this state?
