BlackBerry Pearl 8100
Having bent the enterprise to its will, RIM started to target the consumer segment with the launch of the Pearl in 2006.
One of the most obvious changes brought in for the Pearl was the addition of the trackball, replacing the thumbwheel previously used for navigation.
The Pearl 8100 was also the first BlackBerry to sport a camera, featuring a 1.3-megapixel snapper.

By 2007, RIM had started to include wi-fi in its devices, including this Curve 8320.
As well as wireless connectivity — opening up the possibility of VoIP — the Curve 8320 made a step up in the camera front, with a two-megapixel included.

By 2008, the BlackBerry was making its way firmly into the non-business user segment, as this blinged-up mobile shows.
Luxury gadget maker Amosu gave the BlackBerry Pearl 8120 a very expensive makeover with the Limited Diamond edition, of which only 20 were made.
The device's sides and base are made of 18-carat gold, and it sports 900 hand-cut diamonds.
