so I am AT&T iPhone 3G customer and I am planning to upgrade to the iPhone 4G but the problem is that I am planning to move out to the South Korea soon so I want to know that is it possible to get out of the ETF by showing transfer documentation about leaving country. Now I know that I able to use the iPhone in Korea as the phone is not lock to any of their phone networks and if it works do I have to jail break my device to use all the features. I will be really be glad if anyone here can help me on this
thanks
