    ARC is (with some limitations) backward compatible to iOS 4.
    http://developer.apple.com/library/mac/#releasenotes/ObjectiveC/RN-TransitioningToARC/_index.html

    ARC is supported in Xcode 4.2 for Mac OS X v10.6 and v10.7 (64-bit
    applications) and for iOS 4 and iOS 5. Weak references are not
    supported in Mac OS X v10.6 and iOS 4.
