After some serious research around the web, it seems this year, unlike past years, iPhones are simply not selling for the premium resale values I am used to getting. For example I've sold every iPhone since the first within $50 (plus or minus) of the non-subsidized price. After checking around the web, my iPhone 4S AT&T 64GB seems to be struggling to sell for more than $400. eBay Instant was offering exactly $400 for the iPhone, so in a very uncharacteristic nature (afraid the announcement could cause that number to plumet as the ebay market becomes saturated with them), I sold mine to eBay. So let me know in the poll and thread, did I get a good deal.
FYI - I purchased the phone for $399 with a 2 year re-up at launch.
