BlackBerry is no longer actively working on their classic BBOS platform, with the newest OS 7 now being over two years old. However, the percentage of users on BBOS continues to drift towards the newer versions of the OS.
As of October 73.0% of users are on OS 6+ and 45.2% of users are on OS 7+. Both of these rates are up roughly two percentage points from September.
