Apple released iOS 27.3 beta 1 today, and the iOS 27.3 StandBy mode update is the standout change, pulling the iPhone Duo's redesigned clock faces, colors, and complications onto other iPhone models for the first time, according to 9to5Mac. The feature set, including multiple saved face configurations, new Calendar and Weather faces, and Shared Album support in Photos, had previously been positioned as a hardware differentiator exclusive to the Duo.
