Nokia may be going the Windows Phone 7 way, but it will be a long before we see the device retailing in stores. Meanwhile, the Finnish phone maker is not going to phase out its Symbian offerings, seeing there are more than 200 million Symbian-based devices on the market to date. If you are still holding on to a Symbian smartphone, why not maximize it fully with some of these apps featured here? Note that not all the featured apps are free. All apps are tested on the Nokia N8 touchscreen smartphone.
