Here is a directory of all of the main cabs I have installed on my device.
Tobeychris' Useful Cabs
Certain cabs to note:
Enable Rapi - Disables the security prompts when installing unsigned cabs, etc.
Disable Auto Device Lock - Disables the automatic device lock on sleep.
Disable SMS Sent Notification - Disables the 'Message Sent' notification after sending a text.
Manila Start Menu Unlocker - Allows you to move/remove the first four icons in the start menu.
Enable All Camera Modes - Enables all of the hidden Camera modes (Burst, GPS Photo, Sports, etc).
A restart may be required before the changes are noticed.
