Today, Apple released the iOS 6.1 update for the iPhone, iPad, and iPod Touch. After months of testing, the update is currently available for over-the-air download via Software Update on Apple’s iOS devices.
The 6.1 update includes several bug fixes as well as new features. Most prominently, the update brings LTE compatibility to 36 new iPhone carriers and 23 new iPad carriers worldwide, allowing users with compatible devices such as the iPhone 5, 4th generation iPad, and iPad Mini to take advantage of the faster LTE wireless speeds.
In addition to the LTE improvements, iOS 6.1 update includes Siri-enabled movie ticket purchases via Fandango and support for individual songs downloads from iCloud for iTunes Match subscribers.
The update also adds a new button that lets you reset the Advertising Identifier ( Settings > General > About > Advertising ). Apple explains as follows:
iOS 6 introduces the Advertising Identifier, a non-permanent, non-personal, device identifier, that apps will use to give you more control over advertisers’ ability to use tracking methods. You can reset a device’s Advertising Identifier at any time. And, if you choose to limit ad tracking, apps are not permitted to use the Advertising Identifier to serve you targeted ads. In the future all apps will be required to use the Advertising Identifier. However, until then you may still receive targeted ads.
In addition to the bug fixes and new features, iOS 6.1 packs a variety of security updates for the WebKit, Wi-Fi, as well as other services.
