Apple might have added a bunch of new features for iOS 7.1, but not all of them are available in every single market.
Thanks to Apple’s “iOS 7 Feature Availability” webpage, however, it is possible for international users to easily check which features are supported in which countries. Apple’s CarPlay, for example, is currently available in just thirteen markets, while Siri’s more advanced features — included restaurant and movie reviews — to limited to even less than that.
iOS 7.1 update launched yesterday, and is compatible with the iPhone 4, iPhone 4s, iPhone 5, iPhone 5s, iPhone 5c, iPad 2, iPad 3, iPad 4, iPad Air, iPad mini, iPad mini with Retina display, iPod touch (fourth-generation), and iPod touch (fifth-generation).
The list of which functions are available where can be seen below:
