Supporting older iOS Versions
I plan to drop support for iOS3.X in my next app update (change iOS Deployment Target from 3.0 to 4.0)
I was still targeting iOS 3.0, but can't test anymore my XCode project with older SDK (I can't launch the iOS3.0 simulator).
Do you know if it's possible? What happens to users with iOS 3.X, do they will see the update? (I don't want user complaints)
Users won't be able to install the new update as the minimum version will be updated on the App Store
