Apple has published iOS 6 live, meaning you can update now, either by visiting Settings > General > Software Update on your iPhone 3GS or later, iPod touch 4th gen or later, or iPad, or by plugging into iTunes and checking for updates. iOS 6 offers a long list of new features, including some highlights like system-wide Facebook integration, Appleās new Passbook app, a much more generally useful Siri, and many more besides.
