iFixit reveals that the iPhone 4S has a infrared LED next to the ambient light sensor which is used to keep Siri in a state of constant readiness.
With previous iPhones, the IR proximity sensor would only be activated when in a call, dimming the display and killing the keyboard when you placed the phone to your ear. With the iPhone 4S, the IR sensor is active any time your screen is active.
Siri is ready and waiting to answer her master's beck and call at any time. And in order to be as attentive as a personal assistant ought to be, Apple had to design the proximity sensor to be as vigilant as Big Brother, but as cute as Little Sister. So whenever the screen is active, the proximity sensor is active too. Thus, whenever you raise the iPhone 4S to your face, Siri is ready to take orders.
