The most important improvement is News Feed Support. Its looks more like the current FB on a computer browser.
At first, I thought this was kind of a rip-off cause I liked the status update filter which only showed status updates of friends and none of that other, mostly useless stuff. BUT if you look at the top where it says News Feed, its actually a drop down menu with these other options: Status Updates, Photos, Links.
I like where this is going. This version still supports the calendar and contact linking which is a great feature.
It is available for download at App World or here: www.blackberry.com/facebook.
