The BlackBerry Bold (also known as Bold Touch) is the thinnest BlackBerry device so far at 10.5mm. It runs the BlackBerry OS 7, and utilizes a 1.2GHz CPU, 8 gigs of expandable memory and a 2.8" VGA (640x480) 287 dpi (close to the Retina's 326 dots per inch) capacitive touchscreen. It has a 5 MP autofocus camera with 720p video recording. In terms of looks, it takes after the previous line of Bold devices with no significant changes to the exterior. It's made out of high-quality brushed stainless steel.
The BlackBerry Torch 9810 is a touchscreen device with a slide-down QWERTY keyboard. It has 253 dpi screen, 1.2GHz processor, NFC chip and will be powered by the BlackBerry OS 7. The Torch 9860 will be 11.5mm thick with a 15:9 aspect ratio screen, which is 3.69" with a WSVGA (800x480) resolution with 253 dpi. It also has 5 MP camera with autofocus and 720p video recording. Prior to this official announcement, the Torch 9860 was know by its codename, Monza.
The BlackBerry Messenger 6 ships on the new OS by default. It's quite more social and focuses on easier sharing.
The 9860 and 9900 should officially launch September in the US, UK, most of Europe and presumably Canada, while the 9810 will launch this month by AT&T.
We'll update as soon as more details become clear.
