I\'m running Xcode 4.3.1 iOS-Simulator which originally only supports iOS 5.1.
I need to test my code with iOS 4.3, so I used Xcode\'s \"Install\" feature to install
Another thing you can do is to change the Deployment target to the highest value. This will prevent the Scheme Menu from displaying older versions.
To do this go to: Target->Summary then change the Deployment Target.
