NEW HIRES: Frank Boulben will be the new chief marketing officer at BlackBerry maker Research in Motion Ltd. Kristian Tear is the new chief operating officer.

THE BACKDROP: It's coming as the struggling company looks to regain market share lost to Apple's iPhone. RIM's new CEO described the marketing job as critically important.

VACANCIES: RIM has been without a chief marketing officer since last year and without a chief operating officer since Thorsten Heins was promoted to CEO in January.
