Apple has just rolled out an update to iOS bringing it to version 6.1. The latest iOS brings LTE support for 36 additional carriers offering the iPhone and 23 offering the iPad.

Siri is also updated and allows you to purchase movie tickets right off the app. For now, however, this feature is available only in the US. iTunes Match is updated as well giving its users the ability to download individual songs off iCloud.
Finally, there's a new button that allows you to reset the Advertising Identifier in addition to lots of other minor, under-the-hood bugfixes.
Available as a free download, the iOS 6.1 update is up for grabs for owners of the iPhone 5, iPhone 4S, iPhone 4 and the iPhone 3GS, the iPad (third and fourth generation), iPad mini, iPad 2 and iPod touch (fourth and fifth generation).
