Long Answer:
A cellphone is a portable telephone that provides voice calls and other functions. Indispensable as a communications medium, today's models also function as date books, shopping list organizers, calculators, even as cameras and gaming devices. They are capable of receiving and transmitting voice calls, Internet service (including email and www), short text and pictures messages, and more. And the more advanced models do all this over several protocols and transmission methods. They support GPS, GPRS, Infrared (consumer IR), and even Bluetooth. Not to mention the USB and Wifi support in many models, in addition to dozens of proprietary cable formats.
