4G BlackBerry Torch 9810 coming to AT&T August 21

AT&T will launch the BlackBerry Torch 9810 on August 21. AT&T's website says the Torch is "coming soon," but they've just posted the launch date on their Facebook page. They claim it will be the first 4G BlackBerry. Interestingly, AT&T has not made public a launch date for the 9900 series BlackBerry Bold. What's up AT&T? Verizon and Sprint have both made announcements.
