Another option is to use your carrier's recycling scheme. T-Mobile, Sprint, AT&T, and Verizon all let you return your old phones (and other electronics) to stores. Like Staples, some of the carriers will give you a trade-in value that you can put towards any new gadget you've got your eye on. Between carriers, manufacturers, and electronics stores, you should be able to find somewhere nearby to recycle your phone. Many of these schemes offer mail-in options too.
