Nokia has signed a deal to purchase Intellisync at $5.25 per share. This price puts Intellisync's total value at about $430 million. The buy puts Nokia in a much better position to compete with email and messaging features of BlackBerry and Windows Mobile devices. RIM has said it is not concerned about the merger, even though it puts Nokia in more direct competition with the RIM's popular messaging-centric handset. Analysts expect the enterprise mobile messaging market to explode over the next few years as hundreds of millions of companies embrace mobile email. Nokia also gains access to Intellisync's CDMA applications, which will help Nokia in the US market. Article
