With the official rollout of iOS & iPadOS 16.1.1 a several Wednesdays ago, and the release of iOS 16.1.2 just last week, Apple has made a predictable move this evening by unsigning iOS & iPadOS 16.1 and 16.1.1.
The palera1n jailbreak, albeit intended for developers more-so than the general public, remains one of the only publicly available jailbreaks supporting iOS & iPadOS 15.x. But as more users turn to the newer iOS & iPadOS 16 for the newer features, it only seems appropriate to mention that palera1n co-developer @itsnebulalol has teased successful tweak injection and kernel memory read and write capabilities on a physical iOS 16 device.
Apple released iOS & iPadOS 16.1.1 on Wednesday as a small firmware update for iPhones and iPads alike.
