Apple is currently testing iOS 18.2.1 for the iPhone, with a recently revealed build number of 22C161. This information comes from an anonymous social media account known for accurately sharing iOS-related details. The build number confirms that the update is forthcoming, though its official release may take longer than usual due to the ongoing holiday season.
Typically, when this anonymous account shares a build number, the update is released within a week. However, given the holiday timing, the release of iOS 18.2.1 might be delayed. The account has requested not to be linked, and their wish is being respected in this report.
iOS 18.2.1 is expected to be a minor update focused on bug fixes and security patches, although the specific issues it will address are unclear. At this point, there are no major or widespread bugs known in iOS 18.2, but Apple appears to be working to resolve any smaller issues or security vulnerabilities before the release of iOS 18.3.
In parallel, Apple has started testing iOS 18.3 with developers and public beta testers. This update is expected to be rolled out in January or early February. So far, only minor changes have been discovered in iOS 18.3, signaling that it will not bring significant new features.
