Investment firm Jaguar Financial and some other shareholders owning at least 8% of Research in Motion are calling to oust the company's co-CEOs, Mike Lazaridis and Jim Balsillie, who both own 10% of the company, and potentially sell BlackBerry to the highest bidder. Since last October, Research in Motion’s shares have went down 50% to $24.10, and have slid 58% since the beginning of 2011.
