I know that you were unable to join in the Leaked O.S. and BBM 5.0 love and most links have been removed due to vigilant efforts of the man. So to help you out here is the only active link I could find. This is a destop install, therefor you will need to follow the directions for how to install this app.
GET IT WHILE ITS UP.
I suggest you get download it and save so when its gone you still have it.
