The days are ticking down towards the end of Fairfax Financial’s due diligence period on BlackBerry. Now we have rumors of BlackBerry founder and former co-CEO considering a joint bid for BlackBerry with equity firm Cerberus. This is coming from the Dow Jones after rumors that Cerberus signed an NDA previously together with Mike Lazaridis and Douglas Fregin looking into a bid. This looks like a bid to keep BlackBerry in one piece instead of splitting it up. More of a turnaround effort though they would need serious capital.
