Apple began rolling out iOS 27 in the local market in Australia as of this week. The new build is ready for eligible iPhone models. To set it up, go to Settings. Then tap General. Then choose Software Update. The phone will check for the update and list it if the device is eligible. Not every older device will see iOS 27. The arrival date for iOS 27 is September 14, 2026. So the launch is underway now. Certain iPhone users will get the update immediately. Others are not eligible. The result hinges on the handset.
