iPhone Tip: Tap and hold on a link for a description popup
Safari on the iPhone might be slightly limited in some areas (for example: you can't double-tap contacts in Meebo to begin a chat), but we're discovering all sorts of useful goodies that I don't remember Jobs or the Apple videos ever highlighting. In this screenshot of my iPhone (sorry I couldn't snap a better quality pic), I've tapped and held my finger on a link in Safari, which invoked this handy popup with the name of the linked page, as well as the actual URL. This is a very useful way of translating the typical status bar UI in desktop browsers so it is still accessible on the iPhone for the times you need it, and yet it doesn't take up any valuable real estate during most of the times you don't.
