Abstract :
The mobile phone industry has changed quite a bit since 1998. Back then, most consumer cell phones weren\´t "smart". They were simple phones that couldn\´t be programmed, didn\´t have Web browsers or cameras, and had limited storage. Although you could send digital data over the voice connections, cell phones didn\´t offer data-networking services. Edge, GPRS, Bluetooth, i-Mode, USB, and Wi-Fi weren\´t available for consumer phones, and there was considerable debate within the industry about whether the smart phone could ever replace PDAs such as the Palm Pilot and the Psion Organizer.
