RIM says BlackBerry service restored

Global BlackBerry service is fully restored, Research in Motion said Thursday morning, though there may still be delaysin transmittinginstant messages and emails as thebacklogfrom four days of outages clears.

The company will now look at compensating BlackBerry users, co-CEO Mike Lazaridistold a news conference of reporters and investors, as itstruggles to keep up itsonce-envied reputation for reliability.

SpanishtelecomproviderTelefonica has already said it will compensate its affected customers, in accordance with Spanish law. Britain's Vodafone said it is considering similar measures.

If thosecharges get passed on to Waterloo, Ont.-based RIM, it could face asizable bill.

Outages for RIM's instant messaging service, email and internet browsing started at the beginning of the week in Europe, the Mideast and Africaand spread to Canada, the U.S. and Latin Americaon Wednesday while the company scrambled to restore service.

The outage occurred after a "core switch"and thena backup switch failed, leading to a large backlog of data, but the company did not say Thursday what caused the switches to go down.

Lazaridis spoke onThursday's call alongside fellow co-CEO Jim Balsillie in a rare joint appearance of both executives.

Apple iPhone problems

• As Research in Motion struggled with its BlackBerry service this week, some iPhone users reported problems upgrading to the device's latest operating system.
• Apple released iOS 5 for the iPhone, iPad and iPod Touch on Wednesday, sparking asurge in internet trafficas customers downloaded the software.
• That led to long delays, lasting many hours in some cases,in installing the new operating system, with many users reporting their initial attemptsfailed and they had to retry multiple times.
• In the worst cases,users' iPhoneswere rendered inoperable in the middle of downloading and they reported losing data from the devices.
• Various technology websites said the solution is to reconnect the iPhone to iTunes, which will restoreto the most recent backup. In the severest cases, the phone needs to be put intodevice firmware updatemode.

"You should know we are taking immediate and aggressive steps to prevent this from happening again," Lazaridis said.

Justhours earlier,while servicewas still fritzing,he released a videoexpressing remorseto BlackBerry users affected bythemassiveoutage.

"I apologize for the service outages this week," Lazaridis said inthe 100-secondvideo posted on the company's website and YouTube.

"We let many of you down.... You expect better from us and I expect better from us."

RIM's chief technology officer, David Yach, said messages coming into Europe from Asia and the Americas to BlackBerry users got backed up and started affecting BlackBerry users globally.

Spanish consumer watchdog organization FACUA estimated compensation there should range from 32 cents to $2.67 per day of outage.If that ratewere applied globally to BlackBerry'sroughly 70 millioncustomers,costs could rise to nearly $190 million per dayof service disruption.

RIM shares closed down more than three per cent Wednesdayas investors worried that the problem would undermine the BlackBerry's reputation for reliability.

The stockgave upa further 15 cents, or 0.6 per cent, to $24.12 on Thursday on the Toronto Stock Exchange.
