Google has released Google Earth for the iPhone [not active yet]. The free iPhone software available now from iTunes, displays the same high-resolution imagery as the desktop version for over half the world's population and a third of the world's land mass. The software allows you to tilt the device to adjust the view of the mountainous terrain as well as show the Panoramio layer to browse the millions of geo-located photos. Users can also view geo-located Wikipedia articles, locate themselves on the map using the device's Location services, and search for cities, places, and businesses with Google Local Search. It is available in English, Chinese, Danish, Dutch, Finnish, French, German, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, Spanish, and Swedish. It works on the both the iPhone and iPod touch and requires the iPhone 2.0 software. [iTunes Store link]
