What is a BlackBerry?
The BlackBerry is a handheld wireless device providing e-mail, telephone, text messaging and web browsing services.
The devices are manufactured by the Canadian company Research In Motion (RIM) and are resold by cellular phone companies throughout the world. They fit in the palm of the hand and are operated using a scroll wheel and buttons. The original BlackBerry device had a monochrome display, but the newer models are colour.
While including the usual PDA applications (address book, calendar, to-do lists, etc.) as well as telephone capabilities on newer models, the BlackBerry is primarily known for its ability to send and receive e-mail anywhere it has access to an appropriate wireless network, as well as for its built-in keyboard optimized for "thumbing", or using only your thumbs to type. System navigation is primarily accomplished by the trackwheel (or "thumbwheel"), a scrolling wheel with a "click" function, located on the right side of the device. Some models (such as 7510 and 7520) also incorporate a two-way radio.
