Yes, iOS 4 and greater used with Xcode 4.2 and greater supports ARC. (Weak references are not supported in Mac OS X v10.6 and iOS 4).

ARC is supported on iOS 4.0 and above. You need to use the iOS 5.x SDK but can select iOS 4.3 for the Deployment Target. The one thing that is not supported in 4.x is automatic weak reference zeroing.
