I purchased a wifi iPad about two weeks after it's release from a guy on Craigslist. It was in perfect condition with all original packaging right down to the bag Apple sends you out the door with. I have the receipt where he paid for it with a credit card and I've registered it in my name at Apple.
I've recently been noticing some problems with the wifi connection and it's becoming more bothersome. I read that there are wifi issues with some units and I am thinking that I should make an appointment at the Genius Bar. If they determine that it should be exchanged, will I be able to considering I'm not the person listed on the receipt? I've exchanged other apple products and have never been asked for a receipt so I assume they check for registration and if it matches then no need for a receipt? I suppose I could tell a little white lie and say that it was a friend that picked one up for me on opening day and that would explain the receipt in another name, but I hate to resort to that.
