501.64 million mobile users in China.

"China ended June with 501.64 million mobile users, according to figures from the ministry of information industry.

No comment, except that it is already higher than the Western European figure (obviously a different story if you refer to arpu figures) and that if you discuss standard (DVB-H vs Flo vs whatever), you need to bear in mind China alone has now reached critical mass to impose its own standard."
