Anyone know where I can find stats on how many units are currently running each major version of iOS (1-4). I'm trying to decide if it's prudent to use functionality only available in iOS 4. Thanks!

Most users can easily upgrade to iOS 4 for free, so your app requiring iOS 4 might actually be an incentive for users to upgrade. Only the original iPhone is still stuck as iOS 3.1.3.
