Hi guys. I'm in an odd situation and want to turn to the wisdom of the masses for some advice. I sold my old iPhone 3G on eBay after buying an iPhone 4. I posted pictures of the device (not very detailed). A buyer purchased, and emailed and said he wanted to jailbreak the phone and use it on Verizon. Obviously, he meant he wanted to unlock it. The phone was delivered on Aug. 5, and I never heard from the buyer. But then on Aug. 13, the buyer contacts me and claims there are scratches and dead pixels on the device, and he wants a refund. The device had extremely minimal scratches. Virtually none. There were certainly no dead pixels, as the phone was refurbished just several weeks earlier by Apple. The auction clearly stated the return policy was 3 days. The buyer paid through Paypal. His feedback has a couple dings, but nothing major. I'm assuming he tried to unlock it and is now fabricating issues in order to obtain a refund. Have you ever had an experience like this? What do you think is the best approach?
