Microsoft and Nokia have launched the first application of the mobile-productivity alliance the two companies formed last August. The new application, Microsoft Communicator Mobile for Nokia, is a unified communications client that connects directly with a company’s communications systems to streamline mobile collaboration. Owners of Nokia E72 and Nokia E52 smartphones can download the English version now from Nokia’s Ovi Store. Looking ahead, the two companies plan to deliver Communicator Mobile for Nokia pre-installed on select Nokia smartphones; they also plan to support additional devices, including the new Nokia E5.
