Blackberry Secret Codes
After my little foray into unlocking my old Blackberry Curve I started to think that there were probably other special codes to play around with. I've done a little bit of research and it turns out, yup, there are quite a few special codes to do some random things.
Normally, the signal strength meter is a series of bars like the below image. Hold "Alt" and press "N", "M", "L", "L". To undo just redo
View Source Code
This one every web developer should know. In the Browser, hold "Alt" and press "R", "B", "V", "S"
Help Me! menu
If you ever call up for support chances are you've been told to enter this one. It shows a bunch of info in one place but most of it will be greek to most people. Hold "Alt" and (left) "shift", then press "H".
Display IMEI Code
As far as I know this is really only useful for unlocking a device. Type "*", "#", "0", "6", "#" on the Home screen.
The Event Log is probably only going to be useful if you're a developer or similar. It displays all the last Java goodies that have happened since starting the device. Hold "Alt" and press "L", "G", "L", "G".
Show SIM Information
This code will display the details about a SIM card. You have to enter this code from the SIM Options page and press "M", "E", "P", "D"

From inside a message hold "Alt" and press "V", "I", "E", "W"

This one is really only good if you have a new, unused, Blackberry. It maxes out at the below but if you buy a "new" Blackberry enter this code and verify it. From Status Options page press "B", "U", "Y", "R"
Doing a Hard Reset is like taking the battery out and inserting it again. Handy if you're not in the mood to fuddle with the case. Hold ALT + Right Shift + Del
Validate Contact List
I'm honestly not really sure what these last two do but I'm listing them anyway for completeness. Hold "Alt" and press "V", "A", "L", "D" in address book list
Rebuild Contact List
Hold "Alt" and press "V", "A", "L", "D" in address book list.
These are all the "secret codes" I could find but that doesn't mean there aren't any more. Also, these codes were only verified on the Blackberry Bold 9000 so they may not work with all devices. If anyone has any new ones please leave a comment and I'll update a list.
