From Electronista:

The iPhone 4S sold out in Hong Kong even faster than previously thought, a memo from Ticonderoga Securities’ Brian White indicates. The analyst claims that both the city’s Apple Store and all authorized resellers sold out within a space of three hours; Apple’s local online store states that there is “no supply” of the phone left. Earlier accounts had just the Apple Store selling out by lunchtime.

China isn’t just going to be a huge market for Apple, but for every big company.
People who have been saying the mobile battle between Android and iOS is going to be like desktop battle between the Mac and Windows — and that Apple is going to lose again — have it all wrong.
So many variables have changed since then, it’s a completely different game.
