adeelarshad82 writes "How long does your cell phone carrier retain information about your calls, text messages, and data use? According to data gathered by the Department of Justice, it can be as little as a few days or up to seven years, depending on your provider. The data was made public after the American Civil Liberties Union filed a Freedom of Information Act request related to an investigation into cell phone location tracking by police."
