T-Mobile, the fourth-largest carrier in US by subscribers, today announced that the BlackBerry Curve 8520 will be available for its subscribers on August 5. The BlackBerry Curve 8520 is the successor to the hugely popular BlackBerry Curve PDA phone. The new Curve 8520 still has a full QWERTY keyboard, and a landscape non-touchsensitive LCD screen. Besides that, it also has a touch-sensitive optical trackpad for easier navigation. The Curve 8520 will feature dedicated media keys to control music and videos, the first BlackBerry smartphone to do so.

“People increasingly expect a rich, diverse experience with their phones because they’re using them in new and different ways,” said Travis Warren, T-Mobile’s director of product marketing. “Adding the BlackBerry Curve 8520 to the T-Mobile line-up gives our customers a phone capable of helping bring balance to the chaotic demands of a busy professional and personal life.”

Expectedly, the new Curve phone will support BlackBerry App World, RIM’s weapon agaist Apple’s iTunes, for downloading games, applications, and widgets.
