iOS Version Statistics

It has been longer than 6 months my second app "Ne Ki Bu? Kelime Bulmaca" hit Appstore, and using Flurry I can see change in iOS versions of users.

Here are statistics for Dec 1 2013 through Feb 11 2014.
My app is iOS 6+ (for recent version), you can see that majority of users already updated to iOS 7.
