Where's Waldo?

Sure, there are many ways to determine your location using a GPS-enabled Apple iPhone. But for simplicity and ease of use, I recommend GPS Coordinates, an Apple Web app utility. (Browse Apple Web apps,  All Categories.) "Use GPS Coordinates to get the coordinates of your current position. Your device will use GPS, wireless LAN and cell towers to get the most accurate coordinates, just as Maps and Compass on the iPhone do. After locating yourself you can copy your coordinates to the clipboard and use them in any app you want. Share your location on Twitter, via mail or text it to a friend who uses it within Maps to see your whereabouts." (Credit: "About GPS Coordinates" by Daniel Gattermann, Web app developer.)
