Disappointing quarterly results, including a dismal outlook for Blackberry sales and word that RIM would delay the introduction of new devices, sent its shares down more than 11 percent to their lowest levels in almost eight years on Friday.

Just before those numbers were released, activist shareholder Jaguar Financial called on the company to sell its handset business and monetize its patent portfolio while retaining the high-margin services business. "Jaguar believes that the road map to value restoration lies in a sale of RIM whether as a whole or in separate parts," it said.
