Sources say Apple has formally requested a network access license to sell the iPhone in China, but the license is for a customized model in which Wi-Fi support has been disabled. If that proves true, then Apple (AAPL) has finally bowed to the demands of China’s Ministry of Industry and Information Technology, which has been insisting that the iPhone run only on cellular networks.

As Matt Mathison, an analyst at Wedge Partners, notes, that’s a hell of a concession for Apple, which had no desire to customize the iPhone for the mainland market. “Apple was hellbent on having the iPhone be wifi-enabled,” Mathison told BusinessWeek. “The Chinese government has been just as adamant that it not be.”

Mathison added that now that Apple has conceded to Beijing’s demands, the iPhone may launch in China as much as three months earlier than expected. “We now expect it to come before the Spring Festival in [January] 2010,” he said.

But it’s getting closer.

Interfax reports that Apple (AAPL) is near to obtaining the Network Access License from the Ministry of Industry and Information Technology that would allow the iPhone to be sold in the country. Once the license is secured, Apple needs only to finalize a distribution deal with China Unicom to make good on Cook’s promise, though that has proven problematic.

Apple’s discussions with China Unicom have reportedly been troubled by the company’s distaste for the idea of China Unicom preinstalling non-Apple software–a media player other than iTunes, for example–on its iconic handset. That said, Apple is apparently confident enough in a positive outcome that it’s begun staffing up for a launch. Last week the company posted an ad to its recruitment Web site looking for someone to oversee “iPhone training” across Asia. The position, which will be based out of Beijing, is responsible for designing training programs for iPhone sales teams and retail channels partners.
