iPhone Basics: Jump To The Top of A List or Page
Since iPhone 1.0, tapping the “Status Bar” in Safari would scroll you instantly to the top of a web page. With the iPhone 2.0 update (available for the original iPhone and pre-installed on the iPhone 3G), Apple’s added the same functionality system-wide. Tapping the status bar (the topmost bar where the clock resides) in nearly every application will now scroll you immediately to the top of a list or page. This is especially handy for scrolling through contacts, songs, or anything else with a particularly long list of information.
