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.
BlackBerry Bold 9900
The Bold resurfaced again in 2011 and this time, it featured short-range wireless NFC technology — typically used for contactless ticketing and payments.
The Bold 9900 also came with a capacitive touchscreen and ran the latest version of RIM's operating system, BlackBerry OS 7, which includes an HTML5-friendly browser. There's also a five-megapixel camera onboard.
Announced in 2010 but reaching these shores in 2011 was perhaps RIM's most radical departure yet: the PlayBook.
The tablet, an attempt to capitalise on the wave of slate love initiated by Apple, has a seven-inch display, is 1cm thick and has both front and rear cameras.
The PlayBook was a lonely soul — for 3G connectivity, it had to be tethered to a BlackBerry smartphone using a feature called BlackBerry Bridge, which connected the smartphone and tablet over a secure Bluetooth link.
