A Saudi telecom official has said an agreement between the authorities and the Canadian maker of the BlackBerry smartphone has been reached, averting a ban on the service. He said the deal would involve Canadian firm Research in Motion installing a server inside the kingdom allowing the Saudi government to monitor BlackBerry data. The official of the regulatory authority spoke on Saturday on condition of anonymity because he was not authorised to discuss the details of the deal with the media. The Saudi telecommunications regulatory agency announced earlier this week that BlackBerry’s messenger service would be halted on Friday over concerns that its data could not be monitored.
