How to find BlackBerry Secret Codes
• Name: Decibel meter.
• Description/purpose: Displays your signal strength in decibels, instead of bars.
• Process: Hold "Alt" and press "N", "M", "L", "L" (repeat to reverse the effect).
• Name: Address Book file verification.
• Description/purpose: Checks the data in your Address Book for inconsistencies.
• Process: In the Address Book, hold "Alt" and press "V", "A", "L", "D".
• Name: Address Book data structure rebuild.
• Description/purpose: Forces a data structure re-build in the Address Book...
• Process: In the Address Book, hold "Alt" and press "R", "B", "L", "D".
• Name: View source code.
• Description/purpose: Displays the source code of a Web page.
• Process: In the Browser, hold "Alt" and press "R", "B", "V", "S".
• Name: Help Me! menu.
• Description/purpose: Provides crucial technical information about your device, for when seeking technical support or help in forums...
• Process: Hold "Alt" and (left) "shift", then press "H".
• Name: IMEI display.
• Description/purpose: Displays your device's international mobile equipment identity (IMEI - your serial number) on-screen... Also works from all other GSM handsets.
• Process: Type "*", "#", "0", "6", "#" on the Home screen.
• Name: "Soft" reset.
• Description/purpose: Performs a "soft" reset of your device; the equivalent of doing a "battery pull" (ie. Removing the battery for a few seconds).
• Process: Press-and-hold "Alt", then press-and-hold (left) "shift", then press-and-hold "Del".
• Name: Event Log.
• Purpose: Displays event logs of all the system-level events that occur on your device...
• Process: Hold "Alt" and press "L", "G", "L", "G".
• Name: Device Lock Status
• Purpose: Displays the status of the various locks/restrictions that have been set by your company, device supplier, service provider or Research in Motion (RIM).
• Process: Go to the "Sim Card" settings screen (usually Options-->Device-->Advanced System Settings-->SIM Card) and type "M", "E", "P", "D".
All of these secrets have been tested on the BlackBerry 8800, BlackBerry Curve 8300 and BlackBerry Curve 9320; I would expect them to work on all keyboard-featured BlackBerry devices... The above secrets may or may not work on BlackBerry "Pearl" series handsets.
In some cases, you will need to be on the Home screen when you enter these codes...
If I've missed anything, please add it below...

Cool stuff. I don't know if it did anything different to my address book, but it was cool anyway.

Hey all you pearl users this does work for the pearl. For example on the first code for the change the decibel meter. The code N M L L. The keys on the pearl have two letters. So you type the BN key twice. Then the M L and L keys once and it works. You have to pretend your typing T9 for these codes.

• Name: "Soft" reset.
• Description/purpose: Performs a "soft" reset of your device; the equivalent of doing a "battery pull" (ie. Removing the battery for a few seconds).
• Process: Press-and-hold "Alt", then press-and-hold (RIGHT) "shift", then press-and-hold "Del".
These instructions work for a 8320 curve but its the RIGHT alt key not the leftThanked by:Bruine Suikerbolletje (06-09-2011)

njlx016,
That trick worked on my BlackBerry 8800 (though there was a 1-2 second delay)... Fantastic!
eroccia,
There's only one "Alt" key, but thanks anyway...

Alt + EACE works for QWERTYs, too.

Now is there a way to make the battery meter show a % instead of the existing meter?

These really aren't secret at all. But since no one reads manuals and documentation these days....
