Recently, Engaget shared rumors of TomTom developing it's own GPS module for the iPhone, while the new Google 'My Location' feature now works with the iPhone. Forget TomTom and Google, here's a third-party GPS add-on for the iPhone and iPod Touch that will start shipping in February at the price of 89$US. The great news: the software used is open source, the bad news: it requires your iPhone/iPod Touch to be 'jailbroken' (maybe this will change with the upcoming SDK?). The description: "The iPhone locoGPS module allows jail broken iPhones to finally have GPS functionality. This module is in development and will be shipping in February. All software is open source and more applications are being written every day. The locoGPS module gives you the ability to explore all the benefits of GPS from a device that is small enough to put on a keychain." Of course, you can wonder if the iPhone really needs a GPS, use OpenStreetMap data instead of Google's, read KML/GeoRSS directly on the iPhone.
