Korean carriers SK Telecom and KT have revealed that they are currently in talks with Apple over supporting the next iPhone on their 800 MHz and 1800 MHz LTE networks. Although it seems inevitable that the handset will indeed boast LTE connectivity, as we know from the new iPad, different carriers use different frequency bands all around the world, and so not every LTE network will be supported.
If you’re in Korea, however, it seems there may be support for you… though it may not be available from launch.
