Nokia unveiled four handsets at Mobile World Congress, including the successor to its flagship N95--the N96. The new version has a larger screen, more memory and will cost about $800. Nokia also released the successor to the N73, the N78. The company debuted the 6210 Navigator, which offers advanced GPS features like pedestrian navigation, and the 6220 Classic, which features a five-megapixel camera.

Despite the rise in popularity of touchscreens on mobile phones, Nokia has yet to launch one. When an analyst asked Nokia's CEO Olli-Pekka Kallasvuo why the handset maker is waiting to launch a touch-enabled phone, he replied: "We have said that we will bring out touch products. It's important that you don't bring out gimmicky touch."
