Samsung and SKT had a close relation but it got broken when SKT also decided to bring iPhone 4. Now, iPhone 4 is coming by both SKT & KT and SKT won't support Galaxy S as much as they used to. I am pretty sure that Samsung has enough cash to advertise Galaxy S 2 on TV or everywhere but with less help of SKT, the biggest mobile carrier in Korea, I don't know how many device activation Samsung will get. The activation number of the previous Galaxy S in South Korea is 2.8 million so far.
