Tweaks Blackberry phones with secret codes and hidden keys

Anybody share some secret codes and keys to tweak Blackberry phones. Please give authentic and proven codes only. I'm looking for BB Bold.

Blackberry uses Alt keys to operate any codes. Only for IMEI checking it uses universal *#06# codes.

Here's some secret codes / hidden commands to tweak fast.
ALT+SHIFT+DEL : Reboot system
ALT+LSHIFT+H : System information
ALT+NMLL : This is a good one to show off your BB to others. It will display signal meter to numeric dBm from standard bars. You may find -67 or something like that. It changes to show how closer you're from your network.

If ur bb is hooking frequently then u have 2 clear ur eVent log nd u will do that by holding ALT+LGLG then click on options nd clear event log.....nd ur bb will b hooking relieved hope this will help u a little.

Please does anyone have the activation code for Navita Translator (Blackberry)
