Jailbreaking is a form of privilege escalation, and the term has been used to describe privilege escalation on devices by other manufacturers as well. It is the process of removing hardware restrictions on iPhone, it through the use of software and hardware exploits. It permits root access to the iOS file system and manager, allowing the download of additional applications, extensions, and themes that are unavailable through official package.
Reasons for jailbreaking: -
Jailbreaking of iOS devices is sometimes compared to "rooting" of Android devices. Although the two concepts both involve privilege escalation, they differ substantially in scope. Android devices, with few exceptions, do not natively implement strong technical security measures to prevent users from modifying or replacing the operating system, enabling installation of apps that have not been reviewed or authorized by a central authority such as Google - known as "sideloading" - is a simple user preference.
- Device customization
- Use of handset on multiple carriers
- Installation of malware(Hacking tools)

- Download a free jailbreak utility released by the Pangu jailbreak developers.
- Connect your iPhone to your computer using the USB cable. Tap "Trust" on your iPhone if prompted. This will appear if you are connecting your iPhone for the first time.
- You will need to make a backup in iTunes and check to ensure that you are running the latest version. This will allow you to restore your settings after jailbreaking.
- Start Pangu on your computer and connected iPhone will be displayed in the Pangu window.
- Click "Jailbreak" in the Pangu window and the jailbreaking process will begin.
- This could take up to 20 minutes or more. Do not touch your iPhone or unplug it during the jailbreak process. Your iPhone will reboot after the jailbreak is complete. The reboot will take longer than normal, so don't be alarmed.
- Launch Cydia which is the package manager for jailbroken iPhones. You will need to run it as soon as the jailbreak is complete to finish setting up your filesystem. Your iPhone will reboot again after configuring Cydia.
- Launch Cydia again and tap the "Changes" tab.
- Now that your device is fully jailbroken, you can restore your backup to retrieve your settings and data without losing your jailbreak.
