Apple has dealt a blow to iPhone and iPad users who like to tinker with their devices by discontinuing support for iOS 16.5 and iPadOS 16.5. With the recent release of iOS 16.5.1, Apple has now stopped signing the previous version, making it impossible for users to downgrade if they have already updated to a newer iOS version. This move effectively puts an end to the option of reverting to older iOS builds, a technique often employed by those who jailbreak their devices.
iOS 16.5, which was rolled out on May 18, brought a host of new features and improvements. Notable additions include a Pride theme for the iPhone Lock Screen and a Sports tab in Apple News, catering to a diverse range of user interests. Additionally, bugs related to Spotlight, CarPlay, and Screen Time were diligently addressed and resolved. However, it’s worth noting that iOS 16.5 did suffer from a glitch affecting users who relied on the Lightning to USB Camera Adapter.
Interestingly, Apple discovered two security vulnerabilities that were actively exploited in iOS 16.5. The first vulnerability allowed the execution of arbitrary code with kernel privileges, posing a significant threat to users’ data and device security. The second flaw, specifically in WebKit, was a fix aimed at thwarting the execution of arbitrary code through maliciously crafted web content. By patching these vulnerabilities, Apple demonstrated its commitment to keeping its ecosystem as secure as possible.
In response to these issues, Apple swiftly released iOS 16.5.1 on June 21. This update primarily addressed the bug found in the Lightning to USB Camera Adapter, ensuring a smoother experience for users who rely on this accessory. Additionally, Apple included important security patches to further fortify the iOS ecosystem against potential threats.

The discontinuation of support for iOS 16.5 puts an end to the practice of downgrading for those seeking to jailbreak their devices or rectify issues encountered after updating to the latest iOS version. Downgrading to a previous iOS build has long been a popular technique among users who enjoy customizing their devices beyond the restrictions imposed by Apple. Moreover, it has been a valuable troubleshooting method for individuals who have experienced significant bugs or compatibility issues with newer iOS releases.
While Apple’s decision to stop signing iOS 16.5 may disappoint a certain segment of users, it aligns with the company’s overarching strategy of ensuring device security, stability, and a consistent user experience. By encouraging users to stay up-to-date with the latest software releases, Apple can mitigate potential security risks and deliver the best possible performance across its vast user base.
