Online sources are indicating that Nokia aims to launch their Windows Phone devices in the Chinese market by April 2012.
Nokia launched two models earlier this month. Both of these models are powered with Windows Phone Mango edition.
They are already on sale in some international markets. Nokia has already announced them in India though they are yet to go on sale.
China is the largest mobile phone market in the world and Nokia definitely need to do well there to gain back the market share they are losing to Samsung and other companies.
