Apple has just released iOS 6.1.
LTE support for additional carriers (36 for iPhone, 23 for iPad), the ability to purchase movie tickets through Siri (US-only) and the opportunity for iTunes Match fans to download individual songs from iCloud. Also a new button to reset advertisers.
At first glance nothing seems that new but the bug fixes are substantial. Wifi and loss of service signal are all addressed properly.
Also of note is that Apple TV update bringing cloud integration and support for Bluetooth keyboards. Now where is the Apple TV heading I wonder?
