A couple minutes ago, @tihmstar, the man behind futurerestore and Phoenix Jailbreak for iOS 9.3.5 has released a new UNTETHER package for the iPhone 4S running iOS 9.3.4, making the iOS 9.3.4 the first #Untethered #Jailbreak since #Pangu Jailbreak for iOS 9.0.
What are the advantages of an untethered jailbreak?
Well, an untethered jailbreak does NOT require the user to re-jailbreak after every reboot manually using an IPA, nor it requires the user to side-load the IPA every 7 days. An untethered Jailbreak, once applied, will re-jailbreak the device as it boots after every reboot and will start the appropriate daemons so that the Substrate (with all themes, tweaks, etc.) will already be loaded when you slide to unlock after the reboot. That compared to a semi-untethered Jailbreak that requires you to resign the IPA every 7 days (for free Apple Developers) and to re-jailbreak manually after every reboot.
This untether is not very stable according to tihmstar. He recommends it only for those who aren't afraid / don't really care about bootloops. There is a built-in safety feature, so that, if your device gets in a bootloop, attempting to boot and failing for 10 times will deactivate the kernel exploit so that you can exist the bootloop. Even this way, it is still recommended only for those who don't mind updating to iOS 9.3.5 (jailbroken on 4S) in case of fatal errors.
