Days after Nokia (NYSE:NOK) announced China Mobile would sell two Windows Phone 8 models, Microsoft (NASDAQ:MSFT) has announced a Windows Phone partnership with China Unicom (NYSE:CHU). Analysts estimate WP accounted for only 3% of the Chinese smartphone market in Q3, ahead of the WP8 launches. Separately, Microsoft says it's launching 14 innovation centers in India this week to create a larger base of technical workers familiar with its software, and wants to launch 100 in the country over the next 2 years.
