While it’s not the first turn-by-turn GPS application to offer driving instructions for Apple’s iPhone 3G or iPhone 3GS handset, it’s from TomTom and there’s a brand name behind it. Per Engadget, after starting with New Zealand a few hours ago, the iTunes App Store is now populated with region specific TomTom apps for NZ (US$95), Australia (US$80), US and Canada (US$100), and Western Europe (US$140).

The TomTom application requires iPhone OS 3.0 or later to install and run.

If you’ve tried the application and have any feedback about it, let us know!
