Not sure if this is the best place to post this so please move it if not. I just sold my old iPhone 4 on eBay. My listing clearly stated sales in the US only, but some idiot from Ukraine won the auction. He has perfect feedback with 98 feedbacks. He has been a member for 2 years, but I'm still a little leery. What do you guys think? What's the best way to make sure I'm protected? Will Priority Mail with a tracking number suffice? Thanks.
