According to John Albright of the BlackBerry Paterners Fund, the BlackBerry 9800 Slider, which has yet to be officially named, or, even announced by Research in Motion, will launch on AT&T August 15th.  The first BlackBerry device to sport a touch-screen and a slide down physical keyboard is suspected to be the first BlackBerry that will run RIM’s highly anticipated BlackBerry 6 operating system.
