Apple began rolling out iOS 27 across the country in Australia as of this week. The update is ready for supported iPhone models. To set it up, launch Settings. Then select General. Then choose Software Update. The phone will scan for the update and display it if the device is eligible. Not all older devices will see iOS 27. The arrival date for iOS 27 is September 14, 2026. So the release is live now. A number of iPhone users will see the update immediately. Others are not eligible. The result depends on the handset.
