Ready for some good news out of Waterloo? Well, hold onto your hats, BlackBerry fans, because the latest update to App World introduces a feature that's been a long time coming: the ability to upgrade all apps at once. That's right, now, whenever you see a notification for multiple app updates, you'll no longer want to bellow at the top of your lungs out of sheer frustration, as the "upgrade all" button will manage everything for you with a single click -- which really beats the hell out of the individual update method. The latest version of App World also brings the ability to view and share lists of installed apps with friends via NFC and adds Finnish language support. So go ahead and snag the latest update, and while you're at it, you might as well upgrade all of those apps that you've been neglecting.
