With advances in MOSFET technology enabling smaller integrated circuit chips and the proliferation of wireless mobile networks, IBM engineer Frank Canova realised that chip-and-wireless technology was becoming small enough to use in handheld devices. IBM debuted a prototype device, code named "Sweetspot", on November 23, 1992, at the COMDEX computer and technology trade show in Las Vegas, Nevada, United States. The Sweetspot prototype combined a mobile phone and PDA into one device, allowing a user to make and receive telephone calls, facsimiles, emails and cellular pages. Not only did the prototype have many PDA features including a calendar, address book and notepad, but also demonstrated other applications such as maps, stocks and news. COMDEX show attendees and the press showed interest in the device. The day after Sweetspot's debut, USA Today featured a photo on the front page of the Money section showing Frank Canova, IBM's lead architect and inventor of the smartphone, holding the Sweetspot prototype. After a very successful prototype demonstration at COMDEX, IBM began work on the commercial product, code named "Angler". The IBM device was manufactured by Mitsubishi Electric, which integrated features from its own wireless personal digital assistant and cellular radio technologies while building the IBM device. IBM initially approached Motorola to manufacture the product, but Motorola rejected the offer, concerned that IBM could become a potential rival mobile manufacturer. IBM then approached Mitsubishi to build the device. BellSouth executives gave the finished product its final name, "Simon Personal Communicator", before its public debut at the Wireless World Conference in November 1993. BellSouth Cellular had planned to begin selling Simon in May 1994, but due to problems with the device's software, the Simon did not become available to consumers until August 16, 1994. BellSouth Cellular initially offered the Simon throughout its 15-state service area for US$899 with a two-year service contract or US$1099 without a contract. Later in the product's life, BellSouth Cellular reduced the price to US$599 with a two-year contract. BellSouth Cellular sold approximately 50,000 units during the product's six months on the market. Although the term "smartphone" was not coined until 1995, because of Simon's features and capabilities, it has been retrospectively referred to as the first smartphone.
Features
In addition to its ability to make and receive cellular phone calls, Simon was also able to send and receive faxes, e-mails and cellular pages. Simon featured many applications, including an address book, calendar, appointment scheduler, calculator, world time clock, electronic notepad, handwritten annotations, and standard and predictive stylus input screen keyboards. It features a liquid-crystal display and has PC Card support. Its internal hardware includes the Vadem VG230system-on-a-chip from NEC, MOSrandom-access memory chips from Sony and Hitachi, flash memory chips from Intel and Hitachi, and Cirrus Logicmodem chips.
Accessories
Each Simon was shipped with a charging base station, two nickel-cadmium batteries and a protective leather cover. Optional was a PCMCIA pager card designed by Motorola, an RS232 adapter cable for use with PC-Link to access files from a personal computer, and an RJ11 adapter cable to allow voice and data calls to be made over POTS land-lines. The RJ11 adapter helped users reduce expensive cellular phone bills or make calls where cellular coverage didn't exist in 1994.
The Simon used the file system from Datalight ROM-DOS along with file compression from Stacker. IBM created a unique touch-screen user interface for Simon; no DOS prompt existed. This user interface software layer for Simon was known as the Navigator. The Simon could be upgraded to run third party applications either by inserting a PCMCIA card or by downloading an application to the phone's internal memory. PDA Dimensions developed "DispatchIt", the only aftermarket, third-party application developed for Simon. It was an early predecessor to "Remote Desktop" software. The DispatchIt application costs were US$2,999 for the host PC software and US$299 for each Simon software client.
