Balsillie reiterated that 100 percent of the handhelds sold one day will be smartphones. IDC Canada analyst Kevin Restivo said RIM's results underscore the shift from cell phones to smartphones. "The worldwide smartphone opportunity remains huge ¿ RIM continues to capitalize on it," Restivo said. RIM's better-than-expected report comes as BlackBerry users in North America faced delays in receiving e-mail on their devices Thursday. RIM said that technicians isolated and resolved the issue and that it is investigating the cause. Users were still able to make phone calls, browse the Internet and send and receive text messages. RIM didn't say how many users were affected or how long the outage lasted. RIM said some customers may still experience delays as e-mail queues are processed. RIM, which is based in Waterloo, Ontario, said Thursday that it earned $628.4 million, or $1.10 per share, in the quarter that ended Nov. 28. That compares with $396.3 million, or 69 cents per share, in the same quarter a year earlier. Revenue was up 41 percent to $3.92 billion from $2.78 billion last year. The company's performance surpassed the expectation of analysts polled by Thomson Reuters, who were expecting net income of $1.04 per share and revenue of $3.78 billion.
