In yet another leadership shakeup, RIM's executive vice president of global sales, Patrick Spence, has resigned, the Wall Street Journal reports. According to a statement issued by company representatives, Spence will be "taking a leadership position in a different industry," though no further insight was provided. In the interim, RIM's CEO Thorsten Heins will absorb the role's responsibilities and pass them on to the company's new COO, Kristian Tear, when he starts later this year. Over the last year, RIM has suffered from stock valuation drops, consistent quarterly revenue losses, and the departure of several key executives.

Update: Spence is reportedly joining Sonos as its chief commercial officer.
