Fring has announced that it will soon be adding group video calling to the iPhone and Android versions of its popular mobile voice and video calling app, making it the first app to support multi-way video calling on the iOS platform. Highlighted on the company’s blog, the new group calling feature will allow iPhone and Android users to conduct free live video calls with up to three of their friends over a Wi-Fi or 3G connection. Users start a video call normally and can then add up to two more friends at which point the iPhone screen is divided into four quadrants to display each friend along with the user’s own preview video. The company indicates that it is currently putting the finishing touches on the service and has announced a limited beta to solicit feedback from users ahead of the public launch. Interested users can sign up for the beta by filling out a form at the blog link above; beta applicants will need to provide their device information and list up to three other friends who will be participating in the beta with them.
