Its already a cold day for BlackBerry as the company continues to reshuffle its ranks. The company announced this morning that BlackBerry COO Kristian Tear and CMO Frank Boulben are both set to leave the company, while financial chief Brian Bidulka will be replaced. The news comes three weeks after former CEO Thorsten Heins stepped down after a proposed $4.7 billion takeover deal with Fairfax Holdings fell through. The embattled BlackBerry is now tasked with finding a new direction for its floundering handset business, with a new CEO at the helm and $1 billion in funding from its investors. Interim CEO John S. Chen seems intent on righting the sinking ship, and is cleaning house in the process.
