The Tethered Jailbreak Version is mostly released first. We can do this jailbreak method first with the help of a PC. There is a problem with this method than other jailbreak methods. If your iPhone turns off at some point, when you restart it, all the jailbreak tweaks installed will be disabled. After that, you have to connect the iPhone to the PC or open the relevant jailbreak app on the iPhone (Ex: Pangu) and enable the jailbreak again.
