Ok, so do I need OS X 10.8.2 and iOS 6 to sync my Apple ID and iPhone # in iMessages, or do I just need OS X 10.8.2? I know most have speculated that you'll need both, but the OS X update says it introduces iMessages sync whereas the iOS update doesn't even mention it. I'm asking because I want to hold off upgrading to iOS 6 until a jailbreak is released.
