The launch for the new BlackBerry 10 platform will be held January 30, as smartphone maker Research in Motion tries to regain traction against surging rivals.
The Canadian firm said Monday the launch "will happen simultaneously in multiple countries around the world."
The struggling tech firm will unveil two new smartphones as well as the BlackBerry 10 operating system, aimed at regaining momentum against smartphones from Apple and those using Google's Android operating system.
"In building BlackBerry 10, we set out to create a truly unique mobile computing experience that constantly adapts to your needs," RIM chief executive Thorsten Heins said.
"Our team has been working tirelessly to bring our customers innovative features combined with a best in class browser, a rich application ecosystem, and cutting-edge multimedia capabilities. All of this will be integrated into a user experience -- the BlackBerry Flow -- that is unlike any smartphone on the market today."
The launch comes with RIM, once the dominant smartphone maker, rapidly losing market share.
The BB10 was to have been launched in late 2010, but the company in June announced a delay, a move which means it will miss the critical holiday shopping period.
