Earlier today, Apple released iOS 8.3 to the public, which brought with it several performance improvements and new features. iOS 8.3 brings several improvements to Siri, including new languages. Other features such as diversified emojis, wireless CarPlay and Google’s two-step authentication were also part of the update.
Apart from improvements and new features, the update also included over 39 security patches. One of these patches takes care of a certain Backup bug that allowed hackers to use the backup system and access restricted parts of the file system.
