I have recently released a paid app - which has turned up in the top 10 sports section in the UK for both iPad and iPhone. I have designed this for the very latest version of the iOS - i'm guessing i'm losing sales doing this - have you or anyone else for that matter found any statistics around the numbers of users who download the app from previous versions of the iOS ?

Unfortunately Flurry's new SDK does not collect iOS version info, so we're as much in the dark as you are.

However, 90.9% of our users are listed as having iOS4 devices - I am not sure whether this indicates the iPhone 4, or whether iOS 4 prevents flurry from detecting the device type (in which case this would be an accurate estimate of the number of devices running iOS 4)

I guess that the percentage of users with iOS 3 devices should therefore be at most 9.1% - probably less than that.

Another statistic is that 7.43% of the users had jailbroken devices - I suppose that a significant portion of them would be using iOS 3, as it is so painful to upgrade to iOS 4.

The 'iOS4 devices' listing in Flurry means the operating system is running iOS 4 or greater. It doesn't mean the device is an iPhone 4.
