JaJah is an app for Android (and soon to be iPhone) that lets users make free phone calls to Facebook friends without punching in their phone number. It's neat! The people you call don't even have to have a JaJah account. All you do is select them in the JaJah app and they'll be pinged through Facebook chat.
