Palm Pre... missing screen & lock?

The Screen and Lock app is on the third page of the launcher. Here's a quick tip that will save you a lot of time: When in the launcher or in card view (when you've minimized an app to the desktop) just start typing on the keyboard. Type 'lock' or 'screen'. As you type, universal search will present contacts and apps that match what you type. Good luck, I'm sure you'll have things figured out in no time!
