RIM has officially announced the public beta release of the BlackBerry Messenger (BBM) Social Platform. BB developers can now make use of the massive BBM user base (28 million+ users) for their upcoming apps and projects. The BBM Social Platform will give the developer community access to APIs that will allow them to create apps that feature BBM chatting, file transferring, app sharing, and more. After rumors about the BlackBerry Messenger service arriving on other operating systems, the public release of the BBM APIs bring it one step closer to reality since RIM appears to be gradually opening up their closed platform – keep those fingers crossed. In the meantime, let’s see what the BB developers can come up with using the BBM Social Platform. Head here for more information about the BBM Social Platform.
