January showed virtually no change in the distribution of OS version used by BBOS users from the previous few months. With 55.6% of users running OS 7 there is only a slight increase from the 48.7% that were running OS 7 in January 2014.
Also somewhat inexplicably, the number of users running OS 4.x has not dropped to zero. The percentage of users has been stuck at around 1% for two years now, but should really be at absolute zero by this point. I first wrote about 4.x being dead three years ago, and am baffled that anybody is holding on. (And to be perfectly honest, it is past due for all BBOS users to upgrade to BlackBerry 10).
