Saudi Arabia has reached a deal with BlackBerry smartphone makers on accessing users'data averting a ban on the phone's messenger service. A Saudi official said in Riyadh on Saturday that the agreement involves placing a BlackBerry server inside Saudi Arabia.This will allow the government to monitor users' messages and allay fears that the service can be used for criminal purposes. The official said tests are now on.The deal will have wide-ranging implications for several other countries, including India and the United Arab Emirates, which have expressed similar concerns over the way BlackBerry maker Research in Motion handles its data. They considered the device a security threat because encrypted information sent on the phones is routed through overseas computers making it impossible for local governments to monitor.The United Arab Emirates has announced it will ban BlackBerry e-mail, messaging and Web browsing starting in October.
