Is there any elegant way to “Cut off” support for older iOS operating system versions? When I first published my app the current version of iOS was in the 3.x range. As time progresses continuing to put out updates that support iOS 3.0, while integrating new features found in 4.0 is getting more and more time consuming. Yet I don’t see any way that iTunes or any iDevice will effectively handle this for existing users.
Should I simply upload an update set the minimum iOS to 4.0 (or whatever I choose) and move on?
Most people have already upgraded to iOS 4.x, but there are still a few on iOS 3.x. Leaving those out will surely bring a couple bad App Store reviews (since they won’t be able to update, and even worse: if they delete the app they won’t be able to download the last 3.x-compatible version of your app), but sometimes it’s worth it.
And yes, you’ll need to upload a version that was built with “iOS Deployment Target” set to iOS 4.0.
