That last feature is sure to be a hit with many people, who often have to juggle a BlackBerry for work, as well as their personal phone. I know all too well how that story goes. RIM has worked out a way to securely separate personal content from the work stuff, including email, Facebook, Twitter, and other apps. A newly-updated BlackBerry Enterprise Server 5.0.3 update means that when you leave your job, the IT department only has to wipe the work side of your handset, keeping all the personal data on there.
RIM hasn't confirmed if BlackBerry OS 7 will be available as an update to older models, or if it's only going to be seen on the Bold 9900 and 9930 for now, but I'm sure we'll be hearing—and seeing—more of this update soon enough. [RIM]
UPDATE: Apparently OS 7 won't be swinging its way onto the older handsets. Sorry everyone :(
