The leak-devouring beast that is the Boy Genius managed to get his hands on a few slides from an internal AT&T presentation, packed with a handful of tasty BlackBerry morsels.

First up is the BlackBerry OS 4.5. Currently set to launch around the middle of September, the update brings browser/media player/email UI improvements, HTML email support, Office document editing, calendar lookup, and a handful of other features. Look for it to launch for the 8820, 8310, 8120, and 8300 in the coming weeks.

Also detailed in the presentation is a darker, sapphire-blue version of the previously Tmo-only 8320 expected to hit AT&T sometime near the end of September.

Keep an eye out for the OS updates here.
