So I've never been in a Mac Store before...but I think I'm going to one this weekend... I have an 16GB 1st Generation iPod Touch that DOESN'T work (I think it needs a new battery) and a 1GB 1st Generation iPod Nano... My goal is to trade both of those in for a 32GB "Whatever generation they are on now" iPod Touch.... The thing is I don't have receipts for the two iPods...can I still do it? How much will I still have to pay for the 32GB after I trade the two iPods in? And how do I do it? Do I just go into a store and find some Apple worker and just asked them?
