The iPhone already has a number of paid and subscription GPS navigation services including AT&T Navigator via TeleNav, Navigon, CoPilot, Magellan, Sygic, TomTom, and others, but now Skobbler is bringing free navigation to the platform, which could give Apple a boost when compared with Google’s Android with Google Maps with Navigation OTA, Microsoft’s Windows Mobile with OTA Bing navigation, and Nokia with OVI Maps with navigation with locally stored maps on a memory card–all mentioned solutions offer voice-guided, turn-by-turn instructions. The way that Skobbler is able to deliver free navigation is that the service uses its mapping data from OpenStreetMap, a free, open-source mapping database, rather than from solutions from TeleAtlas or Navteq.
The maps employed by Skobbler are user-edited and user-updated, much like Wikipedia is on the Internet. This allows the entire thing to be free, but then you are relying on the masses to tell you where you’re going and how to get there–and depending where you are, this could either be a really good thing or a very bad thing.
You can download Skobbler by searching for it on your iPhone in the App Store.
