James bond trick and network monitor trick for nokia phone

THE JAMES BOND TRICK
If you short-circuit theleft middle and right pins on the bottom of the phone with all connections touching each other, the Nokia software hangs! The profile "Headset" will be activated. Before you do this just activate the "Automatic Answer" in the headset profile and set the ringing volume to "Mute". Now you can use your phone for checking out what people are talking about in a room. Just place it under a table in a room and call it. The phone receives the call without ringing and you can listen to what people are saying.

Check your software version. You can only continue if you have v4.33, v4.73 or v5.24.

If you have v5.24 then change the address "0378" from "00" to "FF".
