Apple Insider reports this morning that the TomTom GPS application has appeared in the U.S. AppStore. And if you decided to get the external antenna you can even use your iPod Touch as a GPS. That is way cool and way more useful than I had previously thought this was going to be. Kudos for TomTom to make the thing more widely available on the iPhone platform.
The product works with the iPhone 3G and iPhone 3GS, which include an integrated GPS receiver. It will reportedly also be compatible with the first-generation iPhone and the iPod touch once the separate combo hardware kit is made available. TomTom has not yet announced a price for the hardware package.
