Shares of Research In Motion Ltd. (RIMM) surged to a new all-time high Monday as it unveiled the Bold, which is its first major new BlackBerry model in more than a year. RIMM said Monday that the Bold, which has twice the screen resolution of the company's current Curve device, dual-band Wi-Fi and GPS capabilities, will be available from carriers this summer. AT&T Inc. said Monday that it will be the exclusive carrier for the Bold in the U.S.; its 3G network is the only one stateside that is compatible with the first model of the handset.

Jim Suva, an analyst from Citi Investment Research analyst predicted Bold could raise RIMM's quarterly device shipments by 200,000 to 400,000.

Also Monday, RIMM, Royal Bank of Canada and Thomson Reuters PLC said they will invest $150 million in a venture-capital fund for investing in companies making software for BlackBerries and other mobile devices.
