Hey,
We are in beta and allow customers to trade in smartphones for BTC. We're working on adding more electronics to trade in, and should have a new site up in the next four weeks. If you've got an old smartphone in a drawer, see if you can trade it in for bitcoin. We'd love feedback about what we could do better, and we're always looking for new ways to encourage responsible electronics recycling. Check it out here: http://traade.co/coinsy.php
