I found a great new site for recycling and selling your old gadgets like cell phones and ipods. They have a very neat system which takes about 3 minutes for you to complete online and then they will tell you how much your item is worth.
If you are looking to get the biggest buck then you should probably stick with ebay, but for those of you who don't ebay and/or don't want the hassle (and it will be a hassle) then you can just fill out their form and they will pay shipping and send you a check or store credit to your cellular provider.
Its called FLIPSWAP so check it out if you are looking to clean out your gadget drawer for the newer, bigger, better stuff on the market!
PS. They are teamed with the EPA and are very eco-friendly!
