Apple says it sold more than 4 million of its more powerful iPhone 4S units worldwide in the three days after its launch, which the company says is a record for the iPhone line as well as all mobile phones.
The iPhone 4S launched on October 14 with three storage options -- 16GB ($199), 32GB ($299), and 64GB ($399) -- in the U.S., Australia, Canada, France, Germany, Japan, and the UK. Apple will make the phone available in 22 more countries on October 28, and in over 70 countries by the end of the year.
When the iPhone 4 launched in June 2010, it sold 600,000 units in its first 24 hours, and took three weeks to sell 3 million units. The iPhone 4S saw 1 million online orders on its first day, despite being sold in fewer countries that the iPhone 4.
The exterior of the iPhone 4S looks nearly identical to its predecessor, but it features upgraded hardware specifications, like the dual-core Apple A5 processor (also used in the iPad 2), as well as software enhancements and the new voice-controlled assistant Siri.
Apple also noted that over 25 million people have installed its new iOS5 update on iPhones, iPads and iPod Touches, and more than 20 million customers have signed up for its new iCloud backup service, both of which were introduced a day prior to the iPhone 4S' launch.
"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," says Apple's Worldwide Product Marketing SVP Philip Schiller.
