Today, Cydia creator Jay Freeman (Saurik) released an update to his tool Cydia Impactor, which allows the signing and installing of .ipa files to iOS devices.
With it comes a new tool called Cydia Extender, which allows installing and re-signing of .ipa files on-device. However, don’t get too excited by this news; it is not the solution to the 7-day signing problem that many have been waiting for.
The Yalu jailbreak, just like the Pangu jailbreak before it, relies on certificates that have expiration dates. You have to re-sign the jailbreak with Cydia Impactor past the expiration date to keep your jailbroken state.
No matter what kind of certificate you have, whether it’s a regular 7-day certificate or a 1-year developer certificate, it won’t last forever, and a new jailbreak app called CertRemainTime by lululombard can help you keep track of it.
Hot on the heels of the source code being posted to GitHub yesterday, Luca Todesco has posted a very early build of the tool to his website. Work on the GitHub code proceeded quickly after its posting last night, with Todesco and others merging several commits to enable Substrate, add more device support, and streamline the tool.
