The iPhone just got GPS, kinda. Its actually triangulated location detection, but it still works pretty well according to Gizmodo. "This morning, the Navizon GPS app showed up in Installer.app. After creating a username and login (get this: email NOT required), the free app started up, taking about 30 seconds to find my location by measuring the delay between nearby cell towers and using their known locations to pinpoint where I am. Then it pushes your coordinates, by latitude and longitude, to many, many, many decimal places of degrees, to the map application." - Gizmodo
