Blackberry Users Irked by Outage

Research In Motion Ltd. said late Tuesday its technicians are working to resolve e-mail messaging delays on its Blackberry smart phones in North and South America.

Phone calling and texting services appeared to be functional, but users in the Americas have been unable to send or receive e-mail messages. Would-be users tweeted their frustration on social networking site Twitter. Some said they also could not connect to the Internet.

Waterloo, Ontario-based Research in Motion Ltd. said in a statement it apologizes for any inconvenience experienced by customers.

It marks the second time in less than a week that BlackBerry users in North America have had to deal with e-mail outages on their Blackberry devices. Research In Motion said last Thursday that technicians had isolated and resolved the issue and were investigating the cause. RIM didn't say how many users were affected or how long that outage lasted.
