The two current iPhone carriers in South Korea, KT and SK Telecom, are in talks with Apple for LTE support in the next-generation iPhone, according to anonymous officials with the carriers in contact with the Korea Times. The underlying issue is that while the new iPhone is almost guaranteed to support LTE, KT and SK Telecom use separate frequencies for their LTE networks. KT wants Apple to support 1.8GHz, but SK wants 800MHz. SK reportedly sent an official to Apple's Cupertino headquarters earlier this week hoping to secure a deal.
