After weeks of rumors and candid appearances, Research In Motion today announced the official launch of the BlackBerry Bold 9900 and 9930 – two smartphones equipped with the all-new BlackBerry 7 OS.

With the new smartphones, RIM is undoubtedly trying to make up some ground in a market where it has slipped in recent years to competitors Apple and Google. At 10.5 millimeters, the new smartphones are RIM's thinnest to date. Each phone features a 2.8-inch Liquid Graphics touchscreen, a 5-megapixel camera and a full QWERTY keyboard and can be paired with BlackBerry accessories to enhance their functionality.

Under the hood, each device includes a 1.2-gigahertz processor, 8 gigabytes of on-board memory and near-field communication technology for secure identification. The smartphones also support 4G connectivity.

The BlackBerry Bold 9900 and 9930, dubbed the BlackBerry Touch, are the first two devices from RIM to feature the new mobile operating system. With the new OS, RIM has included a "just in time" Javascript compiler, HTML5 support and improved voice-control and web browsing capabilities.

With the rise of Google and Apple, RIM's market share has slipped in recent years. According to research firm IDC, RIM's smartphone market share will dip from 14.9 percent in 2011 to 13.7 percent by 2015.
