A dealer in Handsworth, Birmingham—who would only give his name as “K2″—told me: “I’ve got three Nokia 8210 phones and have been told they can be trusted, unlike these iPhones and new phones, which the police can easily [use to] find out where you’ve been… Every dealer I know uses old phones, and the Nokia 8210 is the one everyone wants because of how small it is and how long the battery lasts.
