Google has released a new beta version of its Mobile Maps application for BlackBerries, Nokia S60 3rd Edition and Windows Mobile smartphones.
This version includes a service called location finder, which uses cell towers to pinpoint user's location. It consumes less power than GPS, works much faster, and can be used indoors. However, it is much less accurate than satellite navigation, but in areas with denser cell tower coverage accuracy is not an issue. The software is also compatible with GPS-enabled handsets.
It is now available for free download.
