This document discusses the history and evolution of smartphones. It begins with an overview of the author's background and credentials in telecommunications. It then covers major technological developments in telephony such as the first telephone demonstrations and exchanges, the development of mobile networks from 2G to 4G, and the rise of smartphones beginning with early devices and the launch of the iPhone. The document argues that while phones today are much more capable than early mobile phones, current smartphones still have limitations and are not fully utilizing new technologies for improvements in areas like voice and video quality, presence capabilities, and intelligent routing.
