Cell phones are tracking and surveillance devices. They all enable the phone system to record where the user goes, and many (perhaps all) can be remotely converted into listening devices. In addition, most of them are computers with nonfree software installed. Even if they don't allow the user to replace the software, someone else can replace it remotely. Since the software can be changed, we cannot regard it as equivalent to a circuit. A machine that allows installation of software is a computer, and computers should run free software. Nearly every cell phone has a universal back door that allows remote conversion into a listening device. (See Murder in Samarkand, by Craig Murray, for an example.) This is as nasty as a device can get. Portable phones make many people's lives oppressive, because they feel compelled to spend all day receiving and responding to text messages which interrupt everything else.
If you need to call someone, ask someone nearby to let you make a call. If you use someone else's cell phone, that doesn't give Big Brother any information about you.
