The base model of the iPhone 4S costs $199 in the U.S. with a two-year contract. It comes with 16 gigabytes of storage. Customers can get 32 gigabytes for $299 and 64 gigabytes for $399. Customers have a choice of white or black.

The phones also debuted Friday in Australia, Canada, France, Germany, Japan and Britain. They are coming to 22 more countries by the end of the month.

The phone has a faster processor and an improved camera compared with last year’s model. It has a new operating system that allows users to sync content without needing a computer. It also includes a futuristic, voice-activated service that responds to spoken commands and questions such as “Do I need an umbrella today?”
