The BlackBerry Bold smartphone isn't the only new Research In Motion offering that AT&T has in the works. Version 4.5 of the BlackBerry operating system will be available soon, according to internal AT&T documents that have been posted on The Boy Genius Report.
Among the key features in the upgraded OS: Docs to Go, which allows you to download and edit Office documents. The upgrade will come to certain handsets in mid-September; see CrackBerry.com for a list of which handsets are expected to run the new OS.
