Saudi Arabia and BlackBerry maker Research In Motion (RIM) are testing three servers in the Kingdom in a bid to resolve a row over the Canadian firm's popular messaging service, a regulatory official told Reuters on Sunday.

'Three servers are being tested, one for each of the three mobile operators. We're waiting for feedback (from the telecoms firms),' said an official from the Communications and Information Technology Commission's technical department.
