Apple is testing iOS 18.2.1 for iPhone, a minor update that fixes bugs and addresses security vulnerabilities. The update is expected to be released in late December or early January. It follows iOS 18.2, which introduced more Apple Intelligence features for iPhone 15 Pro models and all iPhone 16 models, including Genmoji, Image Playground, and ChatGPT integration for Siri. iOS 18.2 also added a useful feature to the Find My app, allowing users to share the location of their AirTag-equipped baggage with select airlines. Apple is also testing iOS 18.3 with developers and public beta testers, expected to release in January with only minor changes.
