NEW YORK ( TheStreet) -- Apple's ( AAPL) iPhone 5 will be available in South Korea on Friday and arrive in China a week later as the consumer tech giant ramps up the rollout of its latest iPhone. Already available in 47 countries, the iPhone 5 will reach more than 50 additional countries in December, according to the Cupertino, Calif.-based company. These include Brazil, China, Russia and Taiwan. In a statement released before market open, Apple confirmed that the fast-growing tech markets are among 33 countries receiving the iPhone 5 on Dec 14. A further 20 countries, including Egypt and Vietnam, will receive the phone on Dec. 21. Launched amid much fanfare in September, Apple has already lauded the iPhone 5 as the fastest-selling phone in history. Despite appearing late in the third quarter, Apple sold an impressive 6 million iPhone 5s during the period, according to tech research firm Strategy Analytics. Apple, however, faces intense competition from smartphone rival Samsung, which has been enjoying great success with its Galaxy S III. Shares of Apple rose 1.42% to $593.6 shortly after the markets opened Monday, outpacing the Nasdaq's gain of 0.6%. --Written by James Rogers in New York.
