Recycling Old Cell Phones?

TK-421 asks: "With the holidays coming up, I think I've read of organizations that take used cellphones and recycle them for use with battered women and other organizations. Does anyone know of the URLs of these places so I can mail out old cellphones I have so they can be put to good use?" Awesome idea! I've got two old phones that I've been wondering what to do with and this is better than tossing them in the trash. What organizations are willing to accept cell phones as donations?
