Research In Motion Ltd unveiled the long-delayed line of smartphones it hopes will put it on the comeback trail on Wednesday but it disappointed investors by saying US sales of its all-new BlackBerry 10 will start only in March.
Chief executive Thorsten Heins also announced that RIM was abandoning the name it has used since its inception in 1985 to take the name of its signature product, signaling his hopes for a fresh start for the company that pioneered on-your-hip email.
"From this point forward, RIM becomes BlackBerry," Heins said at the New York launch.
"It is one brand; it is one promise."
RIM, which is already starting to call itself BlackBerry, had initially planned to launch the new BlackBerry 10 smartphones in 2011. But it pushed the date back twice as it struggled to work with a new operating system.
Ahead of Wednesday's announcements, analysts had said that any launch after February would be a black mark for the Canadian company.
