Motorola Inc. has agreed to acquire privately held Good Technology, a leader in enterprise mobile computing software and service, in a bid to challenge the domination of BlackBerry handheld data device.

Terms of the transaction were not disclosed.

The acquisition of Good Technology will extend Motorola's mobile computing capabilities with Good Technology's wireless messaging, data access and handheld security offerings that provide intuitive and advanced productivity solutions for mobile professionals with enterprise-level device security and management.

"The addition of Good Technology will advance Motorola's vision of seamless mobility," said Ron Garriques, president, Motorola Mobile Devices business.

"Good Technology's software and managed service deliver a rich user experience, low cost of ownership, industry- leading security and enterprise-class support. These competitive differentiators have led many enterprise customers to choose Good Technology."

Motorola and Good Technology deal would allow corporate users of Good Technology's service accessing their e-mail remotely using one of Motorola's newest mobile devices, the Q.

Unlike the market-leading BlackBerry made by Canada's Research In Motion Ltd., Good Technology is based on an open software system that can be used with mobile devices made by a variety of vendors. [1]

Good Technology's software and service offerings have been chosen by more than 12,000 enterprises around the world.

The position of Blackberry maker, Research In Motion, is visibly shaken, as its shares fell as much as 5% in Friday's trading, with much of the drop coming after Motorola announced the Good acquisition, MarketWatch reports. [1]
