Revealing Headphone and Car-Kit Menus

NOTE: If you do these tricks the new menus can not be erased after the procedure. Not dangerous or harmful for your phone but it got to be said

To enable the headset-function, you have to short-circuit the "3" and "4". After a short time there is "Headset" on the display Now, menu 3-6 is now enabled!
To enable the carkit-function you have to short-circuit the "4" and "5". After a short time, "Car" is shown on the display and the menu 3-7 is enabled!!

The James Bond trick

If you short-circuit the left and the right contact with the middle contact ("3", "6" and "9") the Nokia Software hangs! The profile "Headset" will be activated. Before you do this, just active the "auto call receive" function in the headphone 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. Place the phone somewhere under a table in this room and call your phone! The phone receives the call without ringing and you can listen to the words these people are talking about!! Nice hack Mr. Bond, huh?
