Apple began rolling out iOS 27 for users here in Australia as of this week. The new build is ready for supported iPhone models. To install it, go to Settings. Then select General. Then choose Software Update. The phone will scan for the update and list it if the device is supported. Only some older models will get iOS 27. The launch date for iOS 27 is September 14, 2026. So the rollout is active now. Certain iPhone users will spot the update straight away. Others won't. The result is based on the handset.
