RIM is currently working to connect Facebook and Twitter applications with BBM for the BlackBerry users. The company is working seriously on the interconnectivity of the social networking apps with the messenger.
Earlier also many BlackBerry users across the world had interconnectivity of the apps but RIM has not announced anything officially till now. The interconnectivity of social networking apps with BBM will surely be a great ease of use.
Still RIM is expected eagerly to announce this officially but a BlackBerry user (Omercan) has given a glimpse of how the interconnection will look like. Since sometime, new versions of Facebook and Twitter are available but they are still not released by RIM on the BlackBerry App World. The analysts feel that the work is still in progress and this might be the reason of the delay.
The interconnectivity of apps was started initially by the BBM Music which works with the BBM. This app can add friends automatically from the music service to the messenger.
The integration of the apps is not going to offer something that is out of the box but still it will bring about ease of use.
