Verizon says it will stop selling customers’ phone location information to companies that have exposed such data, as well as ultimately passed it on to low level law enforcement. Verizon’s data was included in products which allowed jail wardens and other officials to geolocate nearly any phone in the United States with minimal legal oversight.

The news signals what may be something of a shift in the telco industry, with a tightening of data that has been traded and exploited largely without customers’ direct knowledge.
