NEW YORK (CNNMoney.com) -- Research in Motion shares jumped 4% Wednesday on speculation that the BlackBerry maker will unveil a new smartphone next week.
Websites such as PC World posted articles speculating that the company will unveil the long-awaited Blackberry Bold 9800, a slider phone that is expected to run a new BlackBerry 6 operating system.
RIM (RIMM) teased BlackBerry 6 at its WES conference in April, and since then the company has posted several videos on its blog previewing the touch-based operating system. The new software aims to give BlackBerry parity with features available on most smartphones, including a full Web browser and a modern home screen.
RIM could use a big splash. Though the company has the highest U.S. smartphone market share, at 41.7%, growth has slowed in recent quarters as competitors eat away at RIM's sales.
Apple (AAPL, Fortune 500) clocked in right behind RIM, with a 24.4% market share - a figure likely to grow, thanks to the popularity of Apple's new iPhone 4.
Shares of RIM ended Wednesday at $55.41, a 4.2% gain on Tuesday's closing price.
