Earlier today, Apple released a major iOS update to all modern iPhones, iPads and iPod Touches. iOS 10 brings a range of changes and new features, including an overhaul of the lock screen, however the update process didn't go quite as smoothly as Apple would have liked.
In the first few hours that the update was available, many users upgraded their device only to discover that the updater had temporarily bricked it. An error message appeared on the screen asking users to plug their device into a computer with iTunes to start the restoration process, provided a backup was available to restore.
Apple quickly addressed the problem, and released a statement saying that they "experienced a brief issue with the software update process, affecting a small number of users during the first hour of availability." The company apologized for the inconvenience and says the problem is now resolved.
If you haven't yet updated your devices to iOS 10, it's a good idea to make a full backup before you proceed with the installation process.
When you do successfully install iOS 10, you'll be greeted with a decent collection of new features and upgrades. The lock screen has been improved with widgets and notifications, allowing users to respond to messages without having to fully launch the corresponding app. Other notifications have also been improved with 3D Touch functionality, while almost every stock iOS app has been overhauled and updated.
iOS 10 is now available for the following devices or newer: iPhone 5, 4th-generation iPad, iPad Mini 2, and 6th-generation iPod Touch.
