History
The first BlackBerry device, the 850, was introduced in 1999 as a two-way pager in Munich, Germany. In 2002, the more commonly known smartphone BlackBerry was released, which supports push e-mail, mobile telephone, text messaging, Internet faxing, Web browsing and other wireless information services. It is an example of a convergent device. The original BlackBerry devices, the RIM 850 and 857, used the DataTac network.BlackBerry first made headway in the marketplace by concentrating on e-mail. RIM currently offers BlackBerry e-mail service to non-BlackBerry devices, such as the Palm Treo, through its BlackBerry Connect software.
The original BlackBerry device had a monochrome display, but all current models have color displays. All models except for the Storm, series had a built-in QWERTY keyboard, optimized for "thumbing", the use of only the thumbs to type. The Storm 1 and Storm 2 include a SureType keypad for typing. Originally, system navigation was achieved with the use of a scroll wheel mounted on the right side of phones prior to the 8700. The trackwheel was replaced by the trackball with the introduction of the Pearl series which allowed for 4 way scrolling. The trackball was replaced by the optical trackpad with the introduction of the Curve 8500 series. Models made to use iDEN networks such as Nextel and Mike also incorporate a push-to-talk (PTT) feature, similar to a two-way radio
