The BlackBerry Hub is your one-stop place for all of your messages, emails, and social media notifications, which makes it an integral part of the BlackBerry 10 OS. By using the Hub, you don’t need to open many applications to get things done. Recently, BlackBerry has made the BlackBerry Hub Icon available to download from BlackBerry World for those who have "accidentally" deleted the icon. Although this might seem not important as you can access the Hub by simply swiping to the right from your home screen, this would help some users who somehow deleted their Hub icon and want it back.
We know that all you "leak gurus" would probably just sideload a .bar file from a previous install, but this BlackBerry World solution can make a world of difference for the average user.
