BlackBerry maker Research In Motion has launched Facebook software designed especially for its smartphones to make it easier for users to browse the popular social networking Web site. T-Mobile USA has been chosen as the first carrier to provide the new software to its customers, RIM said on Wednesday.

The application will let users receive Facebook notifications and messages automatically and scroll through them quickly, just like the email service for which the BlackBerry is already well known. Users can also read and compose messages even while off line, RIM said. The feature that lets users upload photos to Facebook will also be integrated with the BlackBerry’s camera and photo management software, RIM said.
