Given the existence of a front-mounted camera on the BlackBerry tablet, it's no great surprise that RIM has a dedicated video calling app up its sleeve, but the company could have simply gone with existing third-party services like Skype.
With its own video-calling application built in-house, RIM could potentially integrate the service with the much-loved BlackBerry Messenger app.
Could this be a PlayBook-only app? RIM hasn't released any handsets with front-mounted cameras yet, so it seems likely for now. But if the PlayBook app proves a success, perhaps RIM will think about sticking cameras on the front of its new phones too.
