A year ago, Apple Inc. said it had sold 9 million of the then-new iPhone 5C and 5S models.
The iPhone is available in the U.S., Australia, Canada, France, Germany, Hong Kong, Japan, Puerto Rico, Singapore and the U.K. It will go on sale in 20 more countries on Sept. 26 and others by the end of the year.
CEO Tim Cook said Monday that demand for the phones has exceeded the company's expectations. Besides larger screens, the new phones offer faster performance and a wireless chip for making credit card payments. The phones start at $199 with a two-year service contact.
