The new Facebook application from RIM will send out a ping with new notifications and messages and also allow you to scroll through them just like you do in regular email. Plus, the photo upload tool is integrated into the camera and photo software.
You can pretty much do almost anything you can on Facebook, thanks to the onscreen icons. With a touch of your finger, you will be able to invite people to join Facebook and accept new friend requests. Just like that it’s done. No adding them later after you’ve gotten home and forgotten everything. Of course you can also poke someone and write on a Wall.
