Joining the likes of Sygic Mobile Maps and Navigon's MobileNavigator Australia - both of which provide turn-by-turn directions and mapping to Australian - the well-known navigation powerhouse TomTom has announced the launch of its app for the iPhone 3G and 3GS. The new TomTom Australia app has already hit the Apple App store, and is available via iTunes for AU$99.95.

TomTom's app for iPhone, which was rumored to be in development for over a year, features the exclusive 'IQ Routes' technology that bases its routes on the practical experience of millions of TomTom drivers, thereby calculating the fastest route and producing the most precise arrival times.

The app also boasts of location-based searches; speed camera alerts; clear voice instructions; automatic re-routing, if required; and route demo. Some iPhone-specific enhancements of the app include - portrait and landscape modes; 'pinch-to-zoom' map controls; and the singular capability to navigate to addresses in the user's address book; and call capabilities from iPhone!

About the newly-launched navigation app, TomTom's Managing Director, Corinne Vigreux, said: "As the world's leading provider of navigation solutions and digital maps, TomTom is the most natural fit for an advanced navigation application on the iPhone. Millions of iPhone users can now benefit from the same easy-to-use and intuitive interface, turn-by-turn spoken navigation and unique routing technology that our 30 million portable navigation device users rely on every day."
