Nokia has launched a new audio-and text-based service that enables Chinese people to download English-language lessons directly onto their cell phones, the Wall Street Journal reported. The paid service, called Mobiledu, is aimed at working adults, who can use the system to study at any time. Beyond lessons, Mobildu offers career tips and how-to advice. It will cost US$0.26 per download, said Marko Vanska, director of Nokia's emerging business unit. Nokia also plans to launch an internet navigation service for cell phones called WidSets in the next six months for the Chinese market. China has about 480 million mobile phone users and the language-learning market is expected to grow to US$3.7 billion by 2010 by total revenue, according to New Oriental Education & Technology Group Inc.
