Facebook Groups
Facebook Groups is designed to let you share and interact with the groups that you are interested in the most. With Facebook Groups on the BlackBerry PlayBook tablet, you can view groups that you’re a member of, post updates, photos and videos, view profiles of group members and send messages, and get notified of new group posts and interactions so you never miss an update.
Improved Media Access
You let us know in your comments and feedback that media viewing and uploading wasn’t intuitive in the application. We heard you loud and clear, and the Facebook app team has made some improvements by adding new photo and video buttons on the Photos tab to make it even easier to view friends’ photos and videos from their Profiles. The photo and video uploading capabilities are also now more apparent on the Photo tab, and are accessible from your Profile or through the Photos feature on the navigation grid. Simply click the Photos or Videos button to upload the corresponding media type.
