Blackberry Bold 9780 to be announced August 3, but leaks of the device with unreleased OS 6 already public

It’s official now that Research in Motion and AT&T are joint-hosting a big event in New York City next Tuesday, August 3rd. This event will very likely mark the official announcement of the new touchscreen Blackberry, as well as the mega-hyped OS 6.

But what looming tech announcement is complete without an early leak? Driphter has posted a YouTube video showing off some of the new OS 6 improvements and additions. (Note that it’s a pre-release version, therefore no the final OS.)
