eBay Instant Sale was conceived by a team of eBay employees in early 2010 who debuted the idea – then called “Resell, Reuse, Recycle” – at eBay’s Innovation Expo. After generating lots of buzz and excitement around the company, the idea was incubated in eBay’s sustainability team, where it was taken from concept to pilot in just over six months. In October 2010, eBay Instant Sale was launched to the public in the United States and quickly became one of the flagship programs within the eBay electronics vertical. The program has been extended to Canada starting December 2011.
To date, the program has generated more than four million offers for devices that range from smartphones to iPads, and has established itself as one of the most competitive electronics trade-in destinations on the web."

$170 for a good condition iPhone4 w/ cable. I got $175 for my iPhone 3 when i sold it on kijiji two years ago when i upgraded to the 4 so this seems reasonable and something to consider pending a review of what local sales are going for when I get my iPhone 5 in a couple of weeks.
