Apple has updated iOS to version 6.1, adding LTE capabilities to 36 additional iPhone carriers and 23 additional iPad carriers around the world.

“iOS 6 is the world’s most advanced mobile operating system, and with nearly 300 million iPhone, iPad and iPod touch devices on iOS 6 in just five months, it may be the most popular new version of an OS in history,” Philip Schiller, Apple’s senior vice president of Worldwide Marketing, said in a press release. “iOS 6.1 brings LTE support to more markets around the world, so even more users can enjoy ultrafast Safari browsing, FaceTime video calls, iCloud services, and iTunes and App Store downloads.”

Additional updates in iOS 6.1 include the ability to use Siri to purchase movie tickets in the US through Fandango. Also, iTunes Match subscribers can download individual songs to their iOS devices from iCloud.

iOS 6.1 is available as a free software update today. iOS 6.1 is compatible with iPhone 5, iPhone 4S, iPhone 4, iPhone 3GS, iPad (third and fourth generation), iPad mini, iPad 2 and iPod touch (fourth and fifth generation).
