I sold my first gen 8GB on Saturday 7/12, in near mint shape, with box, charger, dock & headphones, to CEX, a UK based phone/electronics buyer/seller. They have a shop on Broadway in downtown NYC. They gave me $380 cash. I was pleasantly surprised that they offered that much. It paid for my 16GB 3G, a dock and some screen protectors. I had initally planned on selling the phone on Ebay. I figured I might get around $400 for it, but probably not for much more, and then I would have had to pay Ebay and Paypal fees, and deal with shipping. YMMV. I have no knowledge of CEX's pricing schemes, and make no claims as to what they might pay for YOUR iPhone. I would imagine that at some point the prices will go down. Maybe not. p.s. 1saleaday.com can take a hike. $200 for an 8GB? Puhleeze.
