Apple just confirmed that it will begin to sell the Apple iPhone 5S and the iPhone 5C starting on September 20. The devices will be available from all of Apple’s carrier partners in addition to other retail outlets, such as Best Buy. Pre-orders for the iPhone 5C begin on September 13.

The iPhone will be available in the U.S., Australia, Canada, China, France, Germany, Japan, the United Kingdom and Singapore. The iPhone will be available in more than 100 countries by December of this year, Apple said.

China is a key market, and we assume this means Apple has officially established its partnership with China Mobile. We’ll keep you in the loop as that’s confirmed.
