Facebook has launched its 2.0 app for Blackberry devices (including Playbook). The app can be downloaded from BlackBerry App World. It has got new UI (nice new look). Facebook has improved the chat feature in this app. You can view likes, comment on status. It has got even Facebook Places. The app is well integrated with other BlackBerry apps. The 2.0 app is highly optimized for Playbook to give it tablet feeling. Try it and let us know in the comments?
