Identification and Background
This BlackBerry is a wireless Personal Data Assistant (PDA) rather than a cell phone. It uses a scroll wheel and thumb keyboard for input, and a monochrome LCD screen for output. It is mostly used for communication between coworkers in office buildings.
It is identified by the model number "R900M-2-PW" inside the battery cover, underneath the battery.
