The first iPhone 5s don’t hit the hands of consumers until Friday, but the next generation of Apple’s mobile operating system, iOS 6, is available today for certain versions of the iPhone, iPad, and iPod Touch.

Users can update via an over-the-air download if your device is connected to Wi-Fi, or you can update through the traditional iTunes method.

The upgrade is available for the majority of Apple’s recent iOS devices. The only ones exempt are the original iPad and the iPhone 3G.

First unveiled at the 2012 Worldwide Developers Conference in June, iOS 6 brings a host of new features including the ability to make FaceTime calls over your cellular network (provided your carrier allows it, looking at you AT&T), deeper Facebook integration, an all-new Maps app made by Apple, a digital wallet service called Passbook, and new calling and Siri functionality.

Have you downloaded the update? What feature(s) excite(s) you most in iOS 6?
