Palm webOS Tip: Pref Shortcut
This is especially handy if you have added a ton of the great Palm App Catalog or homebrew applications to your phone and don't feel like flipping through pages of application launcher pages.
Disclaimer: I'm using a Sprint branded Palm Pre running Palm webOS 1.3.1. I don't have access to any other versions of the Pre or the Sprint Palm Pixi. Mileage may vary.
