The iPhone 5c has been completely misunderstood. It was created because Apple wanted more of its phones to work on China Mobile. The iPhone 5 would not work on China Mobile. The iPhone 5c had new colors and plastics but the important change was the RADIO.
The iPhone 5c has always been completely about China Mobile. By the end of this year, all current Apple iPhones will work on China Mobile. That alone was the reason for the 5c.
