I stopped by a friend's house while he happened to be cleaning out the drawers of his desk. Inside he found three cell phones that he no longer needed and so he was going to throw them out. I told him that while he needs to be careful to erase all the data on the phone (he said that there was nothing on it that would be of interest to identity thieves), he could actually sell the phones for a bit of money if he sold it to a place like cell4cash.com
While we found that the Motorola phone was too old of a model to get money, the two Nokia's were worth $5 each so they are being sent off. The Motorola will be donated to a cell phone collection box at the local library.
