Fring has released its free group video calling feature publicly with an update to its iOS application. Originally debuted in a closed beta earlier this month, Fring now allows up to four iPhone and/or Android users to participate in a group video conference over either a Wi-Fi or 3G connection. Users can start a video call normally and then simply add friends to the existing call at which point the screen is divided into four panels to display each of the other three callers along with the current user’s preview video. As with Fring’s normal two-way video calling feature, group video calls run on the Fring network and require that all callers be using the latest version of Fring for iOS or Android. Fring is available from the App Store as a free download.
