Looks like the Korean iPad launch is delayed. KT now has coming soon splash pages instead of the preorder pages it had earlier this week. With 4.2 so critical to launch here, it's not much of a leap to conclude that 4.2 is delayed as well. I don't think it has anything to do with OSX or iTunes updates. I don't plan on updating from my 4.2GM build as I am beginning to think the actual release when it comes will have a few things missing, AirPrint being one of them. As I have AirPrint working with my current setup I won't be rushing to upgrade. If anyone wants to know when 4.2 will be release keep an eye on KT or on other carriers in markets where the iPad has yet to launch.
