Apart from checkra1n, side-loadable jailbreak apps like Odyssey and unc0ver comprise of the overwhelming majority of modern jailbreak tools. While these jailbreak apps are easy to install via a computer with AltStore or Xcode, users demand computer-free options, and that’s the exact reason why signing services such as Jailbreaks.app exist.
As convenient as signing services can be in the short-term, they come with a rather conspicuous caveat: their certificates are often revoked, rendering them useless until a new certificate becomes available. With that in mind, Jailbreaks.app developer iCrazeiOS has released a new and free jailbreak tweak dubbed JBStatusNotifier that will help jailbreakers identify when the Jailbreaks.app certificate becomes revoked or signed.
