BlackBerry officially released OS 10.2.1 this past Tuesday, and despite a few wireless carriers blocking the update for their users, the majority of users who downloaded my apps on Wednesday were already running the newest version of the OS. Taking the average from users of Pixelated and the Stuff I Need apps shows 66.61% of users on the newest OS just a day after it officially launched.
Statistics were collected by BlackBerry World for downloads on January 29th of the free strategy game Pixelated and the free checklist app Stuff I Need. Because this is a snapshot of just a single day, the overall sample size is significantly smaller than for most of the statistics that are posted on this site.
