If you're a developer, you can get your hands on iOS 16.2 beta 4 right now.
Registered developers can download the iOS 16.2 profiles from the Apple Developer Center, and once installed, the beta will be available via an over-the-air update in the Settings app.
The iOS 16.2 update should be released around mid-December.
iOS 16.2 introduces the Freeform app, first announced at WWDC in June. Freeform is a productivity app designed to let iPhone, iPad, and Mac users work together collaboratively in real time. It provides a flexible canvas where multiple participants can add text, photos, sketches, PDFs, as well as other content.
