Vonage, a pioneer of home phone service over the Internet, has a new application for the iPhone and Android phones that provides free calls between Facebook users. Vonage Mobile for Facebook is available as a free download for iPhone, iPod Touch and Android phone users. They sign in with their Facebook username and see a list of Facebook friends who also have the app. Tapping a name places a call to the friend, whose phone rings. The app doesn't need to be running on the friend's phone for the call to go through. The calling works over cellular broadband, so-called 3G, and over Wi-Fi. It doesn't use calling minutes, but will use up data. Versions for BlackBerry phones and for Windows and Mac computers are coming.
