Apple CEO Tim Cook has been spotted taking a tour of an Apple Store in China, leading to speculation that he is there to meet with the country’s three wireless carriers. Citing reports on Chinese micro-blogging service Sina Weibo, AppleInsider reports that a photo of Cook from the Joy City Apple Store in Beijing was posted at 11:00 a.m. “People familiar with the matter” suggested that Cook may be in the area to discuss Apple’s sixth-generation iPhone with China Unicom and China Telecom, the company’s two current carrier partners in the country; it is possible he is also there for talks with China Mobile, the world’s largest mobile carrier and the last carrier holdout for Apple in China.
