It’s a lot less than what we saw with the iPhone in the US and the first tranche of launch countries. But it’s not far from the 2.6 achieved by the iPhone 4. The pricing and 3G penetration in China are far less favorable making this even more impressive.
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.
This is without even being available on China’s largest carrier, China Mobile.
