Got my new 4S, transferred everything over from my 4 using the standard setup, plug into iTunes process. All seems fine, but I can't get Siri to start! When I press and hold the home button, I get the same Voice Control interface that you get on the 4. Holding it up to my ear and asking for something just makes me feel stupid, as nothing happens. (Go ahead - try holding your stapler to your ear and asking it to set a reminder. No response? That's what I'm getting!) Am I missing something obvious? Software is definitely iOS 5.0.
