BlackBerry maker Research In Motion (RIM) has introduced two new BlackBerry Bold smartphones, the 9900 and the 9930.

The new phones are the thinnest ever BlackBerry smartphones at only 10.5mm and come with a stainless-steel frame and glass-weave backplate.

RIM has said that the new smartphones have been designed to offer high-performance and powered by its new BlackBerry 7 operating system.

RIM president Mike Lazaridis said, "The new BlackBerry Bold smartphones and BlackBerry 7 OS are inspired by millions of customers around the world who want the ultimate combination of performance, functionality and style."

Lazaridis said that the phones, whose displays offer 287 dpi, are fully loaded and offer a very fast performance and user experience.

Lazaridis said, "These fully loaded and beautifully crafted smartphones offer a highly refined user experience with blazingly fast performance, a brilliant touch screen and an outstanding typing experience."

RIM has claimed that its Liquid Graphics innovation, used in the new smartphones, delivers up to 60 frames-per-second performance.

The new OS also supports 4G networks, said the company. The devices also support Near Field Communication (NFC) technology, which is used to make contactless payments.

The company said that the 9900 supports HSPA+ connectivity, and the 9930 supports CDMA EV-DO Rev. Both devices support location-based services and augmented reality and contain a feature called Wikitude which displays information intuitively about the place or thing seen through the smartphone’s camera viewfinder.

The BlackBerry Bolds support up to 720p HD video recording and playback. One can also share videos directly from the smartphone to a computer.

"We are excited to be enabling our customers to share important moments and events with family and friends via video calls," said RIM vice president of social networking Tom Goguen.

"Video chat call is the next best thing to being there."

The BlackBerry Bold 9900 and 9930 are expected to be available beginning this summer.

Recently, the company lowered its profit expectations by about 10% for the current quarter, which ends in May. However, the company is sticking to its full-year forecast, saying new models will help it bounce back.
