Another senior executive has parted ways with Research In Motion. The said executive involved with the company’s move into “cloud-based” services, which adds to a string of high-level departures from the BlackBerry maker.

Jim Tobin, senior vice-president for software and business services, which reports directly to co-CEO Jim Balsillie, left the Canadian company months ago, RIM verified on Thursday in an email. It has never legitimately announced the exodus.
