FOR THE RECORD - March 15, 2009

Cellphone bills: David Lazarus’ column in Business on March 8 said a study of high cellphone charges was based on a survey of more than 700 San Diego customers’ bills. In fact, the study, conducted by the auditing firm TeleTruth on behalf of the Utility Consumers’ Action Network and showing an average charge of $3.02 per minute, was based on 134 wireless bills. TeleTruth contends that the methodology of the study supports the validity of the findings that the column reported.
