On Tuesday, during the BlackBerry Live Keynote, the company announced that it will be launching BlackBerry Messenger—BBM—on iOS and Android this Summer. This is a big move for the company, which has found itself increasingly trapped in a badly-built prison of its own making. Now, BlackBerry will make one of its most popular features to users of superior phones who aren’t willing to jump onto BlackBerry’s otherwise lackluster platform. If you haven’t seen BBM working on BB10 yet, you should. It’s a very slickly designed chat experience. According to BlackBerry CEO Thorston Heins, the service will launch only with messaging and groups, but it will later expand to voice, screenshare, and the company’s new company-centric “channels” service. This is a very smart move for BlackBerry as excellent cross-platform chat becomes an increasingly important sphere companies are battling over to win customers.
