Research In Motion Ltd. on Monday showed off a new version of one of its high-end BlackBerrys, updating the Bold with a touch screen and fresh software.
T-Mobile USA said it will carry the BlackBerry Bold 9900 later this year.
Research in Motion is under pressure to update its high-end phones as it's losing out to iPhones and phones running Google Inc.'s Android software. Last week, the company cut its earnings and sales forecasts for the current quarter, saying it's selling fewer and cheaper phones than expected. Its stock plummeted. The fall continued Monday, with the shares losing 55 cents, or 1.1 percent, to $48.10.
Like the original Bold, launched in 2008, the 9900 has a keyboard under a 2.8-inch-screen in landscape orientation. It's thinner than before, at just 10.5 millimeters, making it the thinnest BlackBerry yet.
RIM calls the new software BlackBerry 7 OS and says it provides an easier and faster user experience, with an updated Web browser.
The new phone will come in two versions: one for the type of network used by T-Mobile USA and AT&T, and the other for the type used by Sprint Nextel Corp. and Verizon Wireless. T-Mobile USA is the only carrier to announce that it will carry the phone, so far.
RIM demonstrated the phone on the first day of its BlackBerry World conference in Orlando, Fla.
