Mobile phones will soon surpass personal computers as the preferred device for Internet users in China over the next three years, according to a top official of mobile Internet firm UCWeb.

Yu Yongfu, chief executive of the venture-funded UCWeb, said mobile Internet users in China would jump manifold as 3G services expand in the country.

"With China aggressively pushing 3G services, I think by 2011 most users would use mobile phone, rather than personal computer, to surf the Internet," said Yu.
