I am trying to find out how many of the active iPhone and iPod touch users have at least 3.0 OS installed.
I need to know if the percentage running 2.x is still considerable or not really.
I tried looking into AdMob stats, and other OS usage stats sites, but I can't get to see iPhone 2.x vs iPhone 3.x
I usually use Chitika
