More than three million subscribers are now using the Research In Motion (RIM) BlackBerry wireless platform, with one million subscribers added in less than six months.

"It's an exciting time as BlackBerry continues to enjoy enormous success and rapid growth around the world," said Jim Balsillie, Chairman and Co-CEO, Research In Motion. "With over 50,000 retail points of presence, accelerated geographic expansion and the anticipated addition of 100 new carriers in 2005, we are scaling our operations for the five million and 10 million subscriber milestones."

BlackBerry subscribers reached the one million mark in February 2004 and doubled in less than ten months, reaching two million subscribers in November 2004.

For corporate customers, BlackBerry Enterprise Server software integrates with Microsoft Exchange, IBM Lotus Domino and Novell GroupWise and works with existing enterprise systems to enable push-based wireless access to e-mail and other corporate data. For individuals and smaller businesses, BlackBerry Internet Service allows users to access up to ten corporate and/or personal e-mail accounts (including Microsoft Exchange, IBM Lotus Domino and many popular ISP email accounts) from a single device.
