The Palm Pilot started the handheld PIM (Personal Information Manager) trend, but the RIM (Research In Motion) Blackberry handheld is the device that revolutionized information management by merging it with a mobile phone and incorporating enterprise email on the go. Unified communications seeks to bring that type of on-the-go communications to a whole new level, but the Blackberry was left sitting on the bench…until now. WebMessenger has introduced WebMessenger Mobile for Microsoft OCS, an application for Microsoft OCS which delivers some of the unified communications capabilities of OCS to the Blackberry handheld device. This first generation version essentially only provides IM and IM presence. WebMessenger is working with telecommunications switch vendors to incorporate presence on the phone side as well.
