iOS Jailbreaking is a method followed for the removal of limitations of all mobile devices running the iOS platform. This means that any Apple mobile device in which limitations are identified can be made free of such disadvantages by the use of hardware and software exploits. All forms of second generation Apple televisions and mobile devices like the iPhone, iPad, and iPod Touch can be jailbroken if the required skills and tools are available with the user.

Here we list for you the different types of iOS Jailbreaking methods that developers and users are familiar with:

1. Tethered Jailbreak – If an Apple device starts its backup process on its own, i.e., without the user doing anything in particular, the patched kernel on the device will no longer be seen. This may lead to the device getting stuck in a state in which its features cannot be accessed since it is only partially started, and neither can the device be switched off following the standard method since it has hung up. If the user wishes to start the Apple device completely along with the presence of its patched kernel, iOS jailbreaking is essential. ...
... The device must be jailbroken with the help of a computer and it is important to use the ‘boot tethered’ tool each time the device is turned on. The tethered jailbreak method does not work on Apple devices released prior to the A4 set.

2. Untethered Jailbreak – If iOS running devices are switched off and then turned on immediately, the startup will be complete but the kernel will be patched. However, Apple’s own kernel will be loaded in the device for the first time it is switched on. If the user wants patching of kernels with each reboot of the device, he/she can do so without the help of computers. The process where Apple devices are jailbroken at the end of every reboot is known as untethered jailbreak.

3. Semi Tethered Jailbreak – All iOS devices which have gone through the process of tethered jailbreaking may also be subjected to semi tethered jailbreak solutions. This means that when Apple devices are booted and they do not have a patched kernel, they will be unable to run modified codes for the user. This however will not affect the normal functioning of the Apple device, which means that all features of the device can still be accessed by the user. But if the user is interested in using such features that first require the running of modified codes, he/she must first use a jailbreaking tool and start the device with the help of it. Only when it is jailbroken will the iOS device start its normal functions using a patched kernel.

4. The above three were the main types of iOS Jailbreaking methods. Let us take a look at some other minor processes of jailbreaking Apple devices:

5. iBoot Exploit – This tool provides both user level and iboot level accesses. This type of patching is done in future firmware updates.

6. Userland Exploit - This tool provides only user level access but no iboot level access. The patching is again completed in future firmware updates.

7. Bootrom Exploit – This iOS jailbreaking tool allows both iboot and user level accesses but does not support future firmware updates. Instead, Apple updates the hardware in devices where patching has taken place due to jailbreaking.
