If you explore Apple’s site you might have bumped into their latest section called “Your Life”. Specifically setup to further the knowledge of their current customer base on what is possible on the iPhone; it is also a very good marketing tool for on the fence cellular buyers that aren’t quite sure if they should purchase the iPhone 3G.
The page showcases applications you might use during your day, as well as providing the top paid and free applications available on the App Store.

Perhaps Cydia should also have a “Jailbreak Your Life”
