TomTom has TomTom U.S.A (iTunes Link) in the iTunes App Store for $34.99 for a very limited time.

TomTom’s patented mapping and routing intelligence is at the core of the TomTom App. TomTom is known the world over for the accuracy and extensive coverage of its maps. TomTom maps have been rated highest in terms of quality and reliability. No mobile signal or data plan is required to browse your map and navigate to your destination. And, only TomTom offers IQ Routes, which evaluates routes based on actual traffic speeds rather than posted speed limits, and recommends the fastest route based on the time of the day.

The TomTom App takes advantage of iPhone features and functionality to make navigation even easier, turning your iPhone into a full on TomTom GPS unit. You can see maps and routes easier with iPhone 4 Retina Display support, navigate to your destination easier by selecting contacts straight from your address book or photos from your photo gallery, and take hands-free calls easier while navigating with the App’s multitasking capabilities. It comes with US Maps and features spoken city and street names, advanced lane guidance, TomTom IQ Routes Technology, music controls, full contacts interaction, background navigation, local search provided by Google, a large point of interest database, and much more. iPhone 2G and iPod Touches requires a separate hardware add-on.
