The BlackBerry brand, which used to rein as the mobile king among enterprises with data to protect, has suffered a rough year. In one blow after the next, BlackBerry's future has been more than unstable. In September, Gartner issued a report urging BlackBerry enterprise users to at least devise a mobile back-up plan in the event BlackBerry reaches its final straw. After the company failed to go private, John Chen, former CEO of Sybase, became BlackBerry's interim CEO as Thorsten Heins stepped down. Now the world waits to hear if BlackBerry will make good on its promise to return to an enterprise focus or if the company will continue to spiral out of control.
