Once had this happen.
Though I had the tracking number which showed a package was delivered to the address indicated on the PayPal account.
So my argument was whether or not it was unauthorized, the owner of the Paypal account still received the product from me. I told them I would refund it as soon as they sent it back.
Case was closed in my favor.
Call him out on XDA devs. He looks like he's really active there, that would hurt him the most.
His AIM username is: pipster78

I'm in Canada & used Canada post but when it arrives to the US it was going through the USPS system... I have his signature aswell...
Amazing. YOu finally got a person to make a decision instead of a computer! Some almost unheard of with PP.
I think the problem maybe was it was "unauthorized transaction".
Acording to the PP User Agreement item 11 Protection for Sellers, 11.3 Eligibility Requirements:
To be eligible for Sellers protection you must meet all the basic requirements and c. Unauthorized Transactions Additional Requirements:
•The payment must be marked “eligible” for PayPal Seller protection on the Transaction Details Page.
•You must provide Proof of Shipment or Proof of Delivery.
See: https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=ua/UserAgreement_full&locale.x=en_US#11. Protection for Sellers.
Perhaps you sale was not eligible and that is why? Just a guess.
