Does Anyone know If I need a receipt for my 3G Iphone for warrantee repair? I was #20 on line at the Apple store on day 1 and as many of you know day 1 was a disaster! To make I long story short, Apple told me they can't find a record of my transaction. They could not print a receipt, it wasn't emailed to me, and when I went back to the store and gave them the credit card I payed with(I also used 2 apple gift cards that now have a zero balance), they can't find my transaction. They told me they can't even tell If I actually paid. One week later my credit card was never charged. Well, I am registered with Apple and AT&T, but I don't have a receipt. How important is it to get warrantee service? Can I still add AppleCare? Help!
