Not unless you slam it against your ear. Good news on the proximity detector though (what does it detect? o.O)
It doesn't sense an electrical circuit (since that's essentially what the screen does to sense touch), it has a little IR LED and a receiver. When the IR bounces off your face and into the receiver it knows that there's an object close by (face, pocket, purse, whatever).

It's basically a miniaturized version of the IR beams they have on some electronic keyboards and synthesizers.
