If you like to do business with a Nokia smartphone, you'll want to get yourself Microsoft Communicator Mobile for Nokia, which should make keeping in touch with your work buddies a whole lot easier.You'll need a Symbian-based Nokia E-series handset, not to mention a group of work contacts with a similar phone. Once that's all in place, just head on over to the Ovi store to download it for free and to get chatting.Once intalled, Communicator Mobile allows you to see colleagues' availability. If they're around, click to get in touch, via instant messaging (IM), text message or phone. All statuses are embedded into the Nokia'a handset's list of contacts, so a quick flick through that will tell you who is around for that impromptu meeting, no matter where they are. Yes, you can take part in a meeting from the comfort of your own bed.The launch is the first product from the Nokia/Microsoft alliance, with Microsoft Communicator Mobile initially being offered on the business-friendly Nokia E72 and Nokia E52. Indeed, it will be pre-installed on the smartphones in future. A challenge to the businessman's best friend, the BlackBerry? Possibly, although there's still some way to go for Nokia on that front.
