I haven't been able to find out how many iPhone users are on each device and OS. Anyone have these stats somewhere? Does Apple release this somewhere?

A:
Localytics has a post on their blog that marks the first 2 weeks of adoption, but no real statistics have been released from Apple. I can tell you from experience that one of my apps has the most users on 4.1 (iPhone) and 3.1.3 (iPod) with only nominal representations of previous versions.
Adding some sort of analytics to your app will always answer this question better than published statistics, as different user bases update iOS differently (heck I'm still running 4.0!). Both Localytics and Flurry have free accounts that let you track usage.
