Read, Read, Read Read the quote, "In the world..." iPhones are available all over the world...not just the United States. I have no problem believing that AT&T supports more iPhones than the carriers in other countries do.
I suspect that it will be short lived.
China Unicom has announced that it will be the vendor for the iPhone in China. They purchased 5 million units for selling, before the network is open.
Fortunately, China Unicom is the 'smaller' company, and has only 141 million subscribers, vs 301 million in China Mobile
