I asked as I wonder if a guy bought the Unlocked 650 phone from P1 then sell it off to ebay or friend and buy another Pocket PC phone...so the buyer doesn't have the original order number....Does P1 ask him for the order number when he wants to send the phone back for warranty repair? Or they'll just ask you for your new billing and shipping address with the serial number...then they'll send the phone to the new owner?
