Apple began rolling out iOS 27 for users here in Australia as of this week. This software is live for compatible iPhone models. To install it, launch Settings. Then select General. Then hit Software Update. The phone will check for the update and show it if the device is eligible. Not all older devices will receive iOS 27. The arrival date for iOS 27 is September 14, 2026. So the rollout is live now. A number of iPhone users will spot the update right away. Others won't. The result hinges on the handset.
