Sun Feb 09 11:00:00 UTC 2025: ## Apple Releases Surprise iOS 18.3 Update for iPhone 11 Series via Sideloading Only

**CUPERTINO, CA – February 7, 2024** – Apple has quietly released a second version of iOS 18.3, build number 22D64, exclusively for the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. Unlike the original iOS 18.3 (build 22D63), released on January 27th, this update is not available over-the-air. Users must manually install it via a Mac or Windows computer using Finder.

Initial reports suggest that even attempting an over-the-air update on these devices will install the older build (22D63), not the new one. The update, approximately 8.25GB, addresses specific issues not present in newer iPhone models. Apple’s release notes cite fixes for:

* Calculator app: Repeating the last mathematical operation when the equals sign is tapped again.
* Keyboard: Preventing disappearance during typed Siri requests.
* Apple Music: Stopping audio playback after closing the app.

While Apple hasn’t officially explained the reason for the separate release, speculation points to unresolved bugs affecting the iPhone 11 series, possibly related to Safari or Mail applications, though these haven’t been confirmed. The new build omits the Visual Intelligence and Notification Summary features introduced for newer iPhones in the initial 18.3 release.

Apple recommends that all iPhone 11 series users, even those who have already installed iOS 18.3 build 22D63, update to the new build 22D64 via sideloading to resolve these issues. The company has not provided further details about the nature of the fixes or why this update is specific to the iPhone 11 series.
