RIM said last month the new BlackBerrys are being tested by 50 wireless carriers around the world.
Thorsten Heins, who took over as CEO in January after the company lost tens of billions in market value, had vowed to do everything he could to release BlackBerry 10 this year but said in June that the timetable wasn't realistic. Heins says he can turn things around with BlackBerry 10.
The new BlackBerrys will be released after the holiday shopping season and well after Apple's launch of the iPhone 5, expected to be Apple's biggest product introduction yet.
RIM's platform transition is also happening under a new management team and as RIM lays off 5,000 employees as part of a bid to save $1 billion.
RIM was once Canada's most valuable company with a market value of more than $80 billion in 2008, but the stock has plummeted since, from over $140 per share to around $8. Its decline evokes memories of Nortel, another former Canadian tech giant, which declared bankruptcy in 2009.
Shares of RIM rose 27 cents, or 3.2 percent, to close at $8.81 Monday in New York after rising as high as $9.07 earlier.
