A look at the OS distribution on BBOS, showed no change in March, and for the most part almost nothing has changed in the last six months.
While BlackBerry 10 has shown rapid adoption of the newest operating systems, on the classic BBOS only 48.6% of users are running OS 7 (which itself is almost three years old at this point). And despite being launched half a decade ago, OS 5.0 still continues to account for a significant percentage of the market.
