Early years

In 1973, Theodore George Ted Paraskevakos patented the concepts of combining intelligence, data processing and visual display screens with telephones, outlining the now commonplace activities of banking and paying utility bills via telephone.[4] The first cellular phone to incorporate PDA features was an IBM prototype developed in 1992 and demonstrated that year at the COMDEX computer industry trade show. A refined version of the product was marketed to consumers on 16 August 1994 by BellSouth under the name Simon Personal Communicator. The Simon was the first device that can be properly referred to as a "smartphone", even though that term was not yet coined.[5][14] In addition to its ability to make and receive cellular phone calls, Simon was also able to send and receive facsimiles, e-mails and pages through its touch screen display. Simon included many applications including an address book, calendar, appointment scheduler, calculator, world time clock, games, electronic note pad, handwritten annotations and standard and predictive touchscreen keyboards. In 1996, Nokia released the Nokia 9000, part of the Nokia Communicator line which became their best-selling phone of that time. It was a palmtop computer-style phone combined with a PDA from HP. In early prototypes, the two devices were fixed together via a hinge in what came to be described as a clamshell design. When opened, the display of 640?200 pixels was on the inside top surface and with a physical QWERTY keyboard on the bottom. Email and text-based web browsing was provided

ia their GEOS V3.0 operating system. In the late 1990s though, the vast majority of mobile phones had only basic phone features so many people also carried a separate dedicated PDA device, running early versions of operating systems such as Palm OS, BlackBerry OS or Windows CE/Pocket PC.[1] These operating systems would later evolve into mobile operating systems and power some of the high-end smartphones. In early 2001, Palm, Inc. introduced the Kyocera 6035, the first smartphone in the United States. This device combined the a PDA with a mobile phone and operated on the Verizon Wireless network. It also supported limited web browsing.[15] The device was not adopted widely outside North America.[16] In 2004, HP released the iPaq h6315, a device that combined their previous PDA, the HP 2215 with cellular capability. BellSouth Corporation is an American telecommunications holding company based in Atlanta, Georgia. BellSouth was one of the seven original Regional Bell Operating Companies after the U.S. Department of Justice forced the American Telephone & Telegraph Company to divest itself of its regional telephone companies on January 1, 1984. In a merger announced on March 5, 2006 and executed on December 29, 2006, AT&T Inc. (originally Southwestern Bell) acquired BellSouth for approximately $86 billion (1.325 shares of AT&T for each share of BellSouth)[3] The combined company retained the name AT&T. The merger consolidated ownership of Cingular Wireless and YELLOWPAGES.COM, both of which were joint ventures between BellSouth and AT&T.
