Burt takes a quick look at the history of communication from the cavemen to the alphorn, to the telephone and finally the cellphone. He traces how the cellphone has changed his work and family life as he travels around the world. He also tracks down a series of stories in the United States and Europe that suggests that the cellphone may not be as safe as most of us thought. He meets with experts in England, Italy, France and the United States to find out how we can deal with the problems that are emerging. And finally, Burt follows an Apple developer's conference where they are working on apps to limit your use of their own products.
