RIM shares were up 7.53 per cent at $59.14 in afternoon trading.
RIM co-chief executive Jim Balsillie said the Canadian firm's touchscreen tablet computer, the "PlayBook," will be introduced in North America in the first quarter of 2011 with a global launch in the second quarter of the year.
"There's a lot of demand and we are seeing a lot of interest from international retailers," Balsillie told The Wall Street Journal on the sidelines of the Group of 20 summit in Seoul.
RIM unveiled the Playbook in San Francisco in September as it seeks to compete with Apple's popular iPad and Samsung's recently launched Galaxy Tab.
The PlayBook has a seven-inch (17.8-centimeter) display, smaller than the 9.7 inches of Apple's iPad, and plays Adobe Flash video software, which is banned from the Apple device.
The cheapest iPad costs $499 while the top model is priced at $829.
