And the shakeup at RIM continues. Just last week, former co-CEO Jim Basillie stepped down from the Board of Directors, COO Jim Rowan announced his departure, CTO David Yach retired. This week, the company has confirmed that Senior VP Alan Brennar and Alistair Mitchell, VP of the BlackBerry Messenger service, are stepping away from the company. I’d say “Someone turn the lights out on the way out!” but, eh, those lights all burned out a while ago. [Via: Bloomberg]
