The term refers to a specific iteration of a popular messaging application tailored for devices operating on a particular legacy version of Apple’s mobile operating system. This combination ensures compatibility between the software and the hardware and system software of older iPhone and iPad models. For instance, individuals using older devices might need this specific application build to maintain messaging functionality.
The continued availability of such application versions is important for users who, for various reasons, have not updated their devices to more recent iOS versions. These reasons might include hardware limitations preventing updates, user preference for the older operating system, or simply a lack of awareness regarding updates. These application versions allow these users to continue participating in digital communication and maintain connections despite using older technology.
