Apple's iPhone 5 is rumored for a Sept.21 release date, and the Internet has not stopped buzzing about potential features, alleged leaks and speculation. It is nearly certain that the upcoming iPhone 5 will support 4G LTE connectivity, but there is now more evidence to back up this claim.

Apple has reportedly been negotiating with two mobile carriers in Korea to provide the iPhone 5 through their LTE networks, according to CNET. Officials from SK Telecom and KT allegedly revealed this information to the Korea Times.

"KT is in negotiation with Apple to persuade the latter to support KT's 1.8-gigahertz frequency in Korea for the upcoming iPhone," a senior KT executive said to Korea Times. A KT spokesperson declined to comment.

CNET has contacted Apple for more information on the matter and is waiting for a response.

Both of these carriers are authorized Apple partners selling the iPhone in Korea, and these companies want Apple to utilize their LTE networks. However, supporting 4G LTE is more of a challenge than working with a 3G network since different LTE networks around the world use their own frequencies, as CNET acknowledges.

In the United States, both Verizon and AT&T use 700MHz frequency, and AT&T also uses 2.1GHz. The Korean carriers SK and KT use different frequencies, which could push Apple to launch iPhone models with separate LTE modems to support varying frequencies. This is why the Korean variant of Apple's newest iPad doesn't come with LTE support.

But that doesn't mean LTE service isn't rapidly growing in Korea. At the end of July, the number of Korean LTE subscribers hit the 8.4 million mark and is expected to double that number by the end of 2012, The Korea Times reported. SK reached 4 million subscribers last month, only 44 days after it had achieved the 3 million milestone.

This could add pressure to Apple to produce iPhone 5 models that are compatible with LTE, leaving the Cupertino, Calif.-based company with the decision of whether or not it will be worth the cost and effort.

"If Apple's upcoming iPhone again fails to support LTE bandwidths, then this would be a very disappointing scenario as LTE is everywhere in Korea," an executive from SK Telecom told The Korea Times.

Apple clearly plans to gear up for mass production of its upcoming products, as its main supplier Foxconn Technology Group has invested up to $10 billion in labor in Indonesia. This would allow the Apple supplier to tap into one of the cheapest labor forces in Asia, as Reuters reported on Wednesday.

Foxconn has faced issues of labor unrest and rising wages in its main factories in China, and has attempted to diversify its production in different Asian markets.

"Foxconn already has factories in China and Brazil, and not yet one in Southeast Asia," Ali Soebroto Oentayo, chairman of Indonesia's electronics association, said to Reuters. "I think Indonesia is a right decision from a market perspective."

The Taiwan-based company plans to begin building a plant in October in an industrial zone near Jakarta to assemble 3 million handsets a year, Reuters reports. Foxconn then plans to increase output later on, Indonesia's Trade Minister Gita Wirjawan said to the news wire service on Tuesday. The investment would be between $5 billion and $10 billion.

Foxconn sparked controversy in recent years for producing iPad and iPhones in factory conditions in China dubbed as sweatshops, resulting in worker deaths and suicides. Apple and Foxconn have since then pledged to improve working conditions for its 1.2 million employees in the country, and raise wages by 16 to 25 percent.

Apple is expected to unveil its next generation iPhone 5 alongside an iPad Mini on Sept. 12, with an alleged release date coming on Sept. 21. The company has yet to officially confirm this, but the rumor originated on Apple news blog iMore who cited "sources who have proven accurate in the past." On Tuesday, iMore also reported that Apple will start taking pre-orders for the iPhone 5 on the same day as the announcement.
