BlackBerry has unveiled the latest smartphone to join the Bold line-up, the BlackBerry Bold 9790.

Originally shown off back in June under the codename Bellagio and revealed to developers back in October, the Bold 9790 packs both a touchscreen and QWERTY keyboard, comes with an optical trackpad, BlackBerry 7 OS and a 1GHz processor.

The Bold 9790 is an update to the Bold 9780. It houses a thinner chassis which is meant to make it that little bit better in the hand.

On-board is 8GB of internal memory and this can be expanded through the microSD card slot, which will allow another 32GB.
