Apple sells 9 million new iPhones in three days

Apple sold a record-breaking 9 million new iPhone 5s and iPhone 5c devices in three days, the company announced today. Both new models went on sale on Friday, September 20.

Apple also announced today that more than 200 million iOS devices are now running iOS 7, making it the "fastest software upgrade in history," the company said.

iOS, the "most significant iOS update since the original iPhone," launched on September 18, introducing a new user interface, color palette, and free radio service called iTunes Radio.

Over 11 million listeners have already used iTunes Radio, Apple said, noting the most popular song is "Hold On, We're Going Home" by Drake.

Demand for the iPhone 5s has "exceeded the initial supply," with many online orders expected to be shipped in the coming weeks, Apple said.

"This is our best iPhone launch yet--more than nine million new iPhones sold--a new record for first weekend sales," Apple CEO Tim Cook said in a statement. "The demand for the new iPhones has been incredible, and while we've sold out of our initial supply of iPhone 5s, stores continue to receive new iPhone shipments regularly. We appreciate everyone's patience and are working hard to build enough new iPhones for everyone."

The iPhone 5s is the first smartphone to feature a 64-bit processor. It also includes a fingerprint scanner. The iPhone 5s is available on contract starting at $200 for a 16GB model. The lower-cost iPhone 5c is available in numerous colors beginning at $100.
