crimeandpunishment writes: Facebook and Vonage might become BFF's. Vonage has developed a new application for the iPhone and Android that provides free phone calls between Facebook users. Vonage's CEO says "Essentially, we've given Facebook a voice". Users sign in, see a list of Facebook friends who also have the app, and if they tap on a name a call is placed....and it will go through even if the app isn't running on the friend's phone. The calling, which works over cellular broadband and Wi-Fi, doesn't use calling minutes but will use up data.
