BlackBerry Pearl 3G
2010 saw RIM thinking small, with the introduction of the tiniest BlackBerry and the first of the Pearl range to have 3G connectivity.
The device, known as the Pearl 9100, was aimed at those new to the smartphone market and carried an optical trackpad for navigation as well as a 3.2-megapixel camera.
RIM's first slider device, the BlackBerry Torch, arrived in 2010, sporting a capacitive touchscreen — which supported pinch-to-zoom — and a hard Qwerty keyboard.
The Torch was also notable for being the first to run the latest OS, BlackBerry 6, which featured a refreshed UI and a WebKit browser.
The clamshell form factor resurfaced in 2010 with the launch of the BlackBerry Style — the first flip-phone to have a full Qwerty keyboard.
The smartphone runs the BlackBerry 6 OS but has no touchscreen onboard. Instead, there's a two-inch external display — shown above — where users can check information such as when a new text message has arrived.
