An SK Telecom executive, who preferred to stay anonymous, confirmed the carrier has approached Apple to negotiate an LTE-Advanced capable version of the next iPhone.
According to the unnamed executive "SK Telecom is approaching Apple to put our LTE-A technology on the upcoming iPhone 5S. We are in the middle of negotiations". This means the South Koreans might be getting an LTE-A enabled iPhone 5S in a few months.
Samsung has already launched a faster LTE-Advanced version of the Samsung Galaxy S4 in South Korea. Naturally, some users were left disappointed with the too quick upgrade, but Samsung has simply made sure the Galaxy S4 stay on top of the competition and Apple may have no choice but to follow suit.
The SKT executive suggest Apple might use Qualcomm technology for the LTE-Advanced capable iPhone 5S. We doubt Apple will drop its own chips in favor of Snapdragon 800, but the Cupertino company might use one of Qualcomm's modems.
