Recieved an iPad 2 (32GB + 3G) from a raffle contest at a party Remains unopened No sales receipt Not sure where it was purchased from. First of all, I feel extremely blessed and fortunate. However, with the iPad 3 announcement just around the corner, I want to find a way to upgrade. What's the best way to return an unopened iPad 2 for a refund without a receipt? If I can't return it anywhere without a receipt, what's the best way to sell it for close to full retail value? ($729.00 from Apple Store) My end goal is to upgrade to iPad 3 next month at no loss. Help would be appreciated!
