Good question. I don't know for sure about the version. I will see what I can find out. If you are being told 'not allowed' when you press AA or CCR it's safe to assume it's the Flash Light.
As far as the upgrade, yes, it can be upgraded to a Flash. This will give you the AA and the CCR options. From what I see, it is reasonable pricewise to go ahead and upgrade it to a full Flash. I will keep searching for the Doc's to see what I can find.
