iPhone 5 First Weekend Sales in China Top Two Million

Apple:

Apple today announced it has sold over two million of its new iPhone 5 in China, just three days after its launch on December 14.

Horace Dediu, Asymco:

According to ISI’s Brian Marshall, the iPhone achieved 1.5% penetration of the 3G subscriber base or 15 iPhones per 1000 3G subscribers. If we assumed the same basis (3G subs) that would make the iPhone 5 twice as popular on launch in China than in the US.

Does this indicate China will soon become the largest market for iPhones?
