Yesterday Apple released iOS 6.1 for the iPhone 3GS and up, iPad 2 and up and 4th gen or higher iPod. The update adds support for more LTE carriers, downloading of individual songs from iTunes Match and other improvements and bug fixes. The update is around 70mb and on my 3rd gen iPad took about 5 minutes to install.
