RIM is retooling the software to adapt to the growing number of people who want a smartphone that can fulfill both their personal and professional needs. In an effort to make its phones better suited for this “bring your own device” phenomenon, the new system includes a feature called “BlackBerry Balance.” That enables users to touch an icon on the screen to switch between two different menus of applications and services, one set up for personal activities and the other programmed for work.

“We are convinced this platform will shape the next 10 years as profoundly and as positively as BlackBerry shaped the last decade,” Heins said.

Investors appeared to be heartened by what they heard and saw from RIM Tuesday. The company’s stock gained 30 cents, or nearly 5 percent, close Tuesday at $6.60. That’s still far below the stock’s peak price of about $148, reached in June 2008. Back then, the iPhone was still considered to be a high-tech toy for affluent geeks and the first wave of Android-powered devices had not yet been released.
