Apple has just rolled out the iOS 12.5.8 system update, specifically tailored for the venerable iPhone 5s, a device that's been in the market for nearly 13 years, as well as the iPhone 6, which has been around for approximately 12 years. This latest update is primarily geared towards replacing the internal security certificates of these devices. Should users neglect to upgrade, the pertinent certificates are set to expire in January 2027, potentially leading to a scenario where these older devices experience "functional paralysis."

It's worth noting that the previous system update for the iPhone 5s and iPhone 6 was also a security-focused one, released in January 2023. On the same day as the iOS 12.5.8 release, the iPhone 6s, which made its debut in 2015, also received an update in the form of iOS 15.8.6. This update included extensions for key certificates, further enhancing the device's security.

Apple had previously made a commitment to provide at least five years of security update support from the device's release date. Impressively, the security update support cycle for the iPhone 5s has far surpassed this initial pledge, demonstrating Apple's ongoing dedication to keeping its older devices secure.
