There are hundreds of millions of unused cell phones sitting in junk drawers and glove compartments in America alone. It's silly, they're very fancy, expensive pieces of machinery and when Verizon says "oh, sorry, your old phone won't work with our new plan," all you can say is "Well, fine...but just so you know, I hate you and you're destroying the Earth."
But now there's at least half a solution. CellforCash.com will buy your old unused cell phones from you, as long as you don't wait too long for them to go completely obsolete. Even then, however, they'll recycle your old phone for free.

Just use their search tool, find your phone, enter your address and they send you a box and shipping materials. Once you send your phone to them, they'll send you a check for anything from $5 to well over $100. My LG VX9800 is worth $52. Though, I'm definitely still using it...so no trade-in for me just yet.
You get the best value out of your phone right after you finish with it, so don't let that technology rot, capture the value of your old phone!
