What percentage of iPhone users use each version of iOS

Question

I'm looking for an updated percentage version iOS deployment report. Something like a Chitikia report , but updated.

This information is extremely important for deciding which version of iOS to deploy my application ...

Any idea where to find this? Is Apple publishing such reports for registered developers?

Many thanks!

Just wanted to add this link to later statistics. (Statistics from January 2011).

What is the percentage of iPhone owners on iOS4?

Answer 2

It may be difficult for you to get these statistics. As I understand it, the latest T & C SDK developer does not allow analytic software to collect such data. I know that Flaird no longer builds the iOS version (now it just displays as "Unknown").

I have never seen any data published by Apple developers.

Answer 3

I had the same question. Of course, we could get all those non-technical users to reach 3.2 or higher. From the Chitikia report, it seems that there are many people who still use 3.1.2 and 3.1.3, probably because it was sent on their phone when they bought it.

Back from the dead :)

Finally, Apple provides this information on this page .
