SEOUL, S.KOREA: Apple's iPhone is set to make its South Korean debut in a few weeks after the local regulator cleared the final hurdle for sales of the blockbuster phone in a market home to 47 million mobile phone users.

iPhone's entry could weigh on local market leaders, Samsung Electronics, and LG Electronics, which are also the world's second and third-biggest mobile phone makers.

Korea Communications Commission said in a statement on Wednesday it would grant Apple's South Korean unit a licence that allows collecting information on locations and provide services such as map, phone locating and related marketing.

KT Corp, the country's No. 2 mobile carrier which has been negotiating with Apple to introduce iPhone, said sales could start soon but did not provide a date for the launch.

Korean newspapers said iPhone's sales could start as early as late next week.

With established strength in premium and feature phones, Samsung and LG have also recently boosted their smartphone line-ups to compete with Apple and Blackberry maker Research In Motion.

In April, South Korea also lifted a rule that forced mobile phones sold locally to use a home-grown platform, opening the market to more foreign models.

Prior to the rule change, foreign handset makers avoided the market largely due to re-engineering difficulties. Motorola, Nokia and Sony Ericsson have faced stiff competition from Samsung and LG.

SK Telecom, South Korea's top mobile service operator, said it was still considering selling iPhone and negotiation was under way, but no decision had been made.
