Sure, iPhone 3G is going to offer some solid GPS functionality right out of the box. Apple's updated iPhone site shows off some of the new featuresâ€”most notably turn-by-turn directionsâ€”but TomTom is officially coming to the rescue of users who need a little more from their GPS.
Reuters reports that Dutch-based TomTom is just about ready with an iPhone version of its software that it plans to sell through the iTunes App Store. A price hasn't been set yet, and the company was remarkably low on details, but one can imagine that TomTom can bring some GPS functionality to the table that goes beyond the iPhone 3G's default abilities.
One of the most likely advantages of TomTom's software could be a local database of maps that users can access and customize even if they don't have an internet connection (3G/EDGE, Wi-Fi, or otherwise). TomTom can also bring its own custom array of features and services, including real-time traffic reports (that go beyond the ambiguous red/yellow/green color overlays in Google Maps) and instant messaging for a lifeline while traveling. TomTom's software for other GPS devices can also do things like warn you if you're speeding; perhaps the iPhone could too.
TomTom wasn't specific about when its iPhone client will be ready, but it will be sold for an as-yet undetermined price
Very interesting considering that high end GPS standalone units often cost more than the iPhone itself does
