The SPY-PH-NOKIA 8310 cellphone is an ordinary mobile phone that makes and receives calls as normal but – ‘when the phone is called using the previously programmed spyphone number, it automatically answers without any ringing or lights and the display appears as if it is on ordinary standby.’

In other words when called with a special number it silently goes into transmit mode and broadcasts whatever the mic picks up from the environment.

Sneaky is not the word, eh? You folks getting paranoid enough yet?
