The launch is the single largest launch in RIM’s history, the company said. The new phones — two new models of the BlackBerry Bold and three new models of the BlackBerry Torch — will all run BlackBerry OS 7.

AT&T announced that it will be carrying three 4G BlackBerry smartphones on its HSPA+ network in 2011: the BlackBerry Bold 9900, the BlackBerry Torch 9860 and the AT&T-only BlackBerry Torch 9810.

RIM promised that the new phones are slimmer and faster than the current models.

In terms of notable changes, RIM has added a touch-screen to its Bold models, and two of the new Torch models completely ditch BlackBerry’s signature keyboard and amp up the screen-size. That brings these BlackBerry devices more in line with the industry smartphone standard.

For keyboard enthusiasts, however, the company still has the 9810, which has the same slide-out keyboard/touch display combination as its predecessor.
