The only major countries without an iPhone distribution agreement are Russia and China.
Does that mean the iPhone has a distribution agreement with South Korea? Or that Korea is not considered a "major country"? Apparently the second instance is true, and Korea is not getting the iPhone yet (last paragraph in that link).
For geopolitics, I agree that Korea is not a big fish. But for telecom and mobile services? Please.
It gets tiring dealing with dimwitted editors in New York or wherever that don't get this. Like how everyone squeals about how big the China movie market is growing, when Korea's is well over twice as big. Of course, at the rate China is growing (assuming you believe their statistics)(which I do not), and the rate Korea has stopped growing, China could overtake the Korean movie market in three or four years. But still... the point is Korea has been a bigger movie market than China for a decade (which, considering China's past, essentially means that Korea has always been a bigger movie market than China).
