If you've been following our recent jailbreak coverage you'll know that there is now a jailbreak available for iOS and iPadOS 14, released by the unc0ver team. Another tool is also on the horizon, being worked on by CoolStar. However, the exploit which it uses will only work on iOS and iPadOS 14.0-14.3, not the current 14.4, nor Apple's upcoming firmware, 14.5.
The problem for would-be jailbreakers had been that iOS and iPadOS 14.0-14.3 are no longer signed by Apple, which means users could no longer move to those firmwares through traditional methods. It therefore looked like anyone who wasn't already on iOS or iPadOS 14.0-14.3 was going to miss out on the first semi-untethered iOS 14 jailbreak.
