Just over a year ago, I wrote about getting rid of your old smartphones and PDAs. Number three out of the four ways I suggested was:

Donate to Charity. Help battered women and seniors dial 911 in times of need. Old PDAs are also useful for students. Check out WirelessRecycling.com's FAQ for more info. [emphasis mine]

What's interesting is that Verizon Wireless is providing another way to help victims of domestic abuse through old smartphones. Check out their HopeLine page for more info.
