Given that the software business—and BlackBerry Enterprise Service 10 in particular—is about the only thing bringing in a positive cash flow at BlackBerry, that may be the company's only choice going forward if the go-private deal collapses. We've written off BlackBerry before. But given the company's precarious position as it prepares for a sale, it's increasingly doubtful BlackBerry will emerge from this year in a form that even vaguely resembles the company that changed its name from Research In Motion at the beginning of this year. As if to prove how hard off BlackBerry is, a rumor that Cerberus Capital Management (the same "distressed asset" investment firm that oversaw the death spiral of Chrysler after it was cut loose from Daimler-Benz) was interested in looking at BlackBerry's books today caused BlackBerry's stock price to spike upward, though far short of the $9 a share Fairfax has offered.
