I am not really sure where to post this so i put it here. Ok, i bought an iPod a few months ago at my local applestore. Not thinking about it i didn't file my receipt and am now thinking of echanging it because of an annoying discoloration on the screen, and because of the new iPods. I also paid in cash so i am up a creek if they decide to give me a hard time about it. I remembered that i had them regester it at the store while i was purchasing it, is there a way that i can get a record of the purchase from that? or do you not think that apple will give me a hard time.
