But I understand now that GPS is built in and is active whether you activate it or not. So there is the potential to track you within three meters. Is this so? This wikipedia article on E911 goes into great detail on location tracking of cell phones in the USA: http://en.wikipedia.org/wiki/Enhanced_9-1-1 Some important quotes: 95% of a network operator's in-service phones must be E911 compliant ("location capable") by December 31, 2005. (Several carriers missed this deadline, and were fined by the FCC.[4]) this could have been done via cell phone tower triangulation. However, the article goes on to say: ... In July 2011, the FCC announced a proposed rule requiring that after an eight-year implementation period, at some yet-to-be-determined date in 2019, wireless carriers will be required to meet more stringent location accuracy requirements. If enacted, this rule would require both 'handset based' and 'network based' location techniques to meet the same accuracy standard, regardless of the underlying technology used. The rule is likely to have no effect as all major carriers will have already achieved +85% GPS chipset penetration, and are thus able to meet the standard regardless of their 'network based' location capabilities. ... So, unless you have a REALLY old phone, chances are very high that it has a GPS chipset that is remotely queryable. Bill Bogstad
