Email and Internet service to BlackBerry cellphones in North America stopped working for several hours on Monday. Canada-based Research In Motion, maker of ubiquitous BlackBerry mobile devices that combine telephone, email, and Internet capabilities, notified US and Canadian telecom carriers on Monday afternoon of a major disruption of service. BlackBerry data services "in the Americas" suffered from "intermittent delays" for about three hours and the problem was fixed in the early evening East Coast time in the United States, according to RIM. "No messages were lost and message queues began to be cleared after normal service levels were restored," RIM said in an email response to an AFP inquiry. "RIM continues to focus on providing industry-leading reliability in its products and services and apologizes to customers for any inconvenience."
