The process involves loading a new operating system onto an Apple mobile device, such as an iPhone or iPad. This can be undertaken to upgrade to the latest version, restore a device to factory settings, or troubleshoot software issues. For example, users might undertake this procedure to gain access to new features, security patches, or improved performance offered by a newer version of the mobile operating system.
This procedure is critical for maintaining device security and accessing the most current features and functionalities offered by Apple. Historically, this was primarily achieved through iTunes on a computer. However, over-the-air updates have become the standard, simplifying the upgrade process for the majority of users. Keeping devices current with the latest operating system mitigates vulnerabilities and optimizes performance.
