iPhone 5 sales hit 5 million

Apple's latest iPhone is on fire. The Cupertino, California-based company has announced that three-day weekend sales of the iPhone 5 have exceeded 5 million units. The thinnest and lightest iPhone ever launched September 21 behind a record-setting preorder campaign.

The iPhone 5 bested the first-weekend sales of the iPhone 4S, which came in at a then-record-setting 4 million units. The iPhone 5 is currently available in the United States, Australia, Canada, France, Germany, Hong Kong, Japan, Singapore, and the United Kingdom. It will launch in 22 additional countries on September 28.

Apple reiterated that demand for the iPhone 5 has surpassed supply, noting that some who preordered a unit will not receive it until October.

Apple also announced that more than 100 million iOS devices have been updated with iOS 6, the latest iteration of the company's mobile operating system. It offers a range of new features, including a proprietary Maps app, as well as updates to Siri, Facetime, and Mail.
