Tech made possible through app/router combo
Third-party GPS support for the iPod touch is coming soon, an announcement claims. GeoLife says it has submitted a new version of Navmii to the App Store, which -- in tandem with a PosiMotion G-Fi router -- should allow a Touch to access turn-by-turn car navigation. The Touch lacks both the GPS and 3G receivers found in the iPhone, normally rendering it incapable of handling directions while driving.
The G-Fi costs $99, and converts GPS data into a local-area Wi-Fi signal which surrounding devices can access. A Navmii app with US maps is expected to cost $40, while a UK version should be priced at £30. Also promised is a special hardware/software bundle, which should be announced once Apple has approved Navmii.

For the $150...
you could buy an inexpensive dedicated GPS and use it in your car so you can save your IPT battery for something more important...like playing with your virtual Zippo or Lightsaber.
