BlackBerry Maker Research in Motion has let go some senior vice presidents and vice presidents, reports the Globe and Mail. “Lots of high level people within RIM were let go today,” a source told the newspaper. “Quite a few. Big shake up.”

Sales and marketing staff, which were targeted for layoffs in the summer, have been targeted yet again, according to this person.

RIM's latest quarterly results were, as everyone thought they'd be, bad.  The Wall Street Journal says:

The company reported a fourth-quarter adjusted profit of 80 cents a share, while revenue fell 19% to $4.2 billion. Both fell shy of analysts’ expectations. The BlackBerry maker said it shipped 11.1 million BlackBerrys last quarter and over 500,000 PlayBook tablets.

Previously, RIM postponed its annual investor presentation – usually revealed during the Blackberry World in May — until it launches the BlackBerry 10 later this year. The new Blackberry is expected to use faster and more efficient chipsets, but will rely on the same OS used in the disappointing Playbook.
