Apple Is Holding A Separate iPhone Event In China On September 11th 

9to5Mac:

One day after sending out invites to press in the US for its iPhone event scheduled for September 10 in Cupertino, Apple has just sent invites to Chinese media outlets inviting press to a special event in the country on September 11. Attached to the invite (above) is the same image and tagline hinting at iPhones in various colors that Apple included on the invites for its US event. Not only will it be the first time Apple hosts such an event in China, it is also a good indication that China Mobile, the world’s largest telecom, could soon finally announce a deal with Apple to bring the iPhone to its approximately 700M subscribers.

The iPhone 5C is squarely aimed at prepaid markets. China is the biggest prepaid market.
