Google announced the release of version 2 of its Google Maps application for mobile phones. New in v2.0 is a beta version of Google's "My Location" technology, which uses cell tower ID information to provide users with their approximate location, helping them determine where they are, what's around them, and how to get there.

Location information makes mobile mapping and search faster and more convenient, but the most common source of location information to date -- GPS technology -- is supported on fewer than 15 percent of the mobile phones expected to be sold in 2007. With Google's new My Location technology, users who don't have GPS-enabled mobile phones will now be able to take advantage of the added speed and convenience afforded by location information. The My Location technology also complements GPS-enabled devices, as it delivers a location estimate faster than GPS, provides coverage inside buildings (where GPS signals can be unreliable), and doesn't drain phone batteries as quickly as GPS.

The My Location technology takes information broadcast from cell towers and sifts it through Google-developed algorithms to approximate a user's current location on the map. This approximation is anonymous, as Google does not gather any personally identifiable information or associate any location data with personally identifiable information as part of the My Location feature. The feature can also be easily disabled by anyone who prefers not to use it.

Phones with a GPS facility will display the location as a small blue dot on the screen. Where cell-id is used, then a larger pale blue zone is highlighted which shows the approximate coverage area of that cellsite.
