The move to offer LTE and HSPA+ versions of its PlayBook guarantees access the most advanced wireless data networks in the world, including all major carriers in North America.
The first version of the PlayBook, with WiFi and Bluetooth but no cellular connection, is set for launch in March and U.S. carrier Sprint Nextel will sell a version for its WiMAX network in the summer.
The WiFi-only version can connect to a user's existing BlackBerry smartphone to access its data and use its wireless connection, but that may give carriers little incentive to subsidize or advertise the PlayBook aggressively.
Evolved High Speed Packet Access (HSPA+) is used by AT&T and T-Mobile in the United States and Rogers, BCE Inc and Telus in Canada. Long Term Evolution (LTE) is an all-IP standard that Verizon Wireless, among others, has started to deploy.
Both standards are designed to carry the increased amount of data needed for video streaming and large file downloads at improved speeds.
RIM also said on Monday it has bought Seattle-based business social networking company Gist for an undisclosed sum, as it seeks to bolster its position versus Apple, Google's Android, and the newly announced combination of Nokia and Microsoft in the fiercely competitive mobile telecoms market.
RIM also said its App World online store is now available in 27 more countries for a total of 101 and now has more than 20,000 applications on offer.
The Waterloo, Ontario-based company has struggled to compete with the consumer-focused app offerings of Apple's App Store and Google's Android Marketplace.
Shares in RIM, which announced the PlayBook in late September, have jumped almost 50 percent since early that month. They were down 1.1 percent at C$65.16 on Monday afternoon.
INVESTING AGAIN IN FUND
RIM also said it will contribute to a second $150 million tranche of the BlackBerry Partners Fund, which will focus on investing in mobile-computing start-up companies.
The second tranche of the fund is expected to be launched in June. RIM did not disclose how much money it is providing, but said it was a "lead" commitment. The Ontario Venture Capital Fund has also invested, the fund managers have said.
Thomson Reuters and Royal Bank of Canada joined RIM as lead contributors to the first tranche of the fund, which has invested in 13 mobile start-ups in North America, Israel and Ireland since 2008. Neither company was immediately available to comment.
One of those start-ups, social gaming company SocialDeck, was bought by Google in August.
The co-managers of the fund said in October they saw opportunities to tap into growing mobile markets such as India, China and Brazil.
