Word of a big exec shakeup at RIM leaked out
just ahead of the company's quarterly earnings late last month -- something that was then quickly confirmed in said earnings report
. It looks like that wasn't the end of it though, as RIM has now also confirmed the departures of two more high-level executives. That includes Senior Vice President Alan Brenner, who will be leaving after an unspecified transition period, and Alistair Mitchell, a VP for RIM's BBM service who has already left the company. No word on any further departures to come (willing or otherwise), but given Thorsten Heins' talk of a "comprehensive review" it certainly doesn't seem like the most remote of possibilities.
