Four million Apple iPhone 4S sales in three days

Apple announced today it has sold over four million of its new iPhone 4S devices just three days after its launch on 14 October.

Apple also announced that iOS 5, its improved operating system, has more than 25 million users in the first five days of its release, and over 20 million customers have signed up for iCloud, the free cloud service that stores content and pushes it out to other iOS 5 Apple devices.

iPhone 4S is off to a great start...

The iPhone is available today in the UK, US, Australia, Canada, France, Germany, and Japan. It will be available in 22 more countries on 28 October, and more than 70 countries by the end of the year, Apple said.

"iPhone 4S is off to a great start with more than four million sold in its first weekend - the most ever for a phone and more than double the iPhone 4 launch during its first three days," said Philip Schiller, Apple's senior vice president of Worldwide Product Marketing.

The iPhone's new features include a dual-core A5 processor, an eight mega-pixel camera, speedier downloads, longer lasting battery life, and Siri, a voice recognition technology.
