Earlier this week, Apple updated its iOS distribution numbers once again to show that 63% of active iOS devices have now upgraded to iOS 8. That’s a 7% increase over November and another sign of steady growth for what has been a problematic update for many users. Distribution of iOS 7 has fallen in proportion with the rise of iOS 8, down to 33% as of December 8th. Distribution of earlier versions has shrunk to 4%, which means that 96% of active iOS devices are on one of the two latest versions of the mobile operating system.
