Frequent "teleconferencers" with BlackBerry smartphones take note: Research In Motion (RIM) today released a beta version of its new BlackBerry Mobile Conferencing application. With the app, which integrates with the BlackBerry OS, RIM handheld users can quickly and easily invite other BlackBerry users to a teleconference, add new teleconference info to their mobile calendars and connect to conferences with a single click. In addition, the software helps you quickly reconnect to an ongoing conference if you're ever disconnected.
