The iPhone app, which will be unveiled on Thursday, is called (BFF) and is expected to appear in the Apple App Store soon, once Apple approves it. Broadcast for Friends will also work with iPads.

Application users can apply pre-configured filters to alter the colors and mood of the video. The broadcasts don't have a time limit.

The free application can be used, for example, to broadcast wedding ceremonies, public meetings, artistic performances, parties and the like. Ustream doesn't plan to display ads with the application. Viewers can send comments in real time to the broadcaster.

Users can set different access levels for their broadcasts, including making them available to their Facebook friends, to themselves only, or to everyone. Users can also save a recording of the broadcast so it can be viewed later on demand on their Facebook Timeline.
