Fresh to BlackBerry's Beta Zone portal, RIM has introduced BlackBerry Mobile Conferencing, an app designed to take the (apparent) mystery out of joining a conference call -- thus putting the jobs of many executive assistants in jeopardy. Scheduled telephonic meetings are pushed to an employee's phone, automatically blocking out time in the calendar. When it's collaboration time, all attendees are reminded with a handy 'join now' button that automatically dials into hosted conferences -- complete with access codes and all. Should your call be dropped, dialing back in is just another click away. Yeah, we know you should already be the boss, but if yours can't figure this one out, feel free to start arranging that corner office in the back of your mind.
