Submission + - Google locates mobile phone users with cell towers (networkworld.com) 1
jbrodkin writes: "Google today launched a GPS-like service for smartphones that uses cell tower ID information to track the location of mobile phone users and direct them to nearby destinations. The technology, an extension of Google Maps, "takes information broadcast from cell towers and sifts it through Google-developed algorithms to approximate a user's current location on the map," Google says.
Google seems to anticipate concerns from privacy rights advocates, and has promised not to associate location data with any personally identifiable information. This new mobile version of Google Maps is available in beta."
