It’d be, so far, the most expensive deal in China’s Internet history if Baidu successfully bought 91 Wireless (Update: Baidu finally paid $1.85 billion.). Xiong developed 91 Assistant after joining NetDragon. 91 Assistant got much traction as Chinese users with jailbroken iPhones could download paid apps from it for free. It reportedly had three million users in early 2010 that accounted for over 90% of jailbroken iPhones in China. 360 Mobile Assistant, actually, was developed with the help from 91, but it seems the partnership didn’t last long.
