South Korean sales of the iPhone are moving as quickly as Samsung's flagship Omnia II, separate statments. KT on Thursday said it had sold about 400,000 iPhones in the past four months, or about 100,000 per month since January. The rate was enough to come on par with Samsung's Omnia II, which Samsung earlier this week said had sold 600,000 units so far in six months of being in subscribers' hands.
