The link below shows some of the options. I sold mine last weekend on eBay for $560 minus fees. I've sold most of my previous phones on eBay, but I've sold a few on Craigslist as well. Wouldn't recommend Craigslist though because of all the no-shows and the bargain downers. I've even had requests asking me to give them my phone for free.
