Answer 1

ARC runs with 5.0 or higher, Storyboard also needs iOS 5. Therefore, both are potentially available with the iPhone 3GS and above.

EDIT: Obviously, ARC is also compatible with iOS 4.0 and above, once you don't use weak. I briefly tested it, seems to work. That would mean that the iPhone 3G would also be compatible.
