Jailbreaking is perfectly legal. If you wanted, you could put your iPhone in a toaster - we don't recommend it, but it's your property and you're entitled to do whatever you want with it. And that includes installing Pangu and customizing your device.
Let's take a look at how to free your smartphone or tablet from iTunes. This is a jailbreak for iOS 9.2, 9.3.3 and ios 10 on 64-bit iPhones and iPads, so update your device as normal if you're not on the latest firmware already. Also keep in mind 64-bit iOS devices include the iPhone 5s and higher, the latest iPod Touch, the iPad mini 2 or higher, the iPad Air or higher, and the iPad Pro.
If you you so much interested in jailbreaking and you don’t want to brick a brand new iPhone, another option is buying a reconditioned iPhone. We have an entire post dedicated to this subject, complete with links out to all the best places to buy certified reconditioned iPhones.

Jailbreaking your iOS device can go wrong, so please, follow these instructions at your own risk. We cannot be held responsible for any damage made to your phone while following these instructions.
Step 1: Backup Your Device
Hook up your iPhone, iPod or iPad to your computer and perfume a full iTunes sync before going any further. The good news about jailbreaking is that if anything goes wrong, you can use this backup to put your device back exactly as it was. It's a great safety net that removes much of the risk.
Step 2: Turn off Find My iPhone on your iOS device.
Go to Settings > iCloud and disable Find My iPhone. This helps stop the iPhone from phoning home.

Right now the installer is only in Chinese but an English version is coming very shortly.
Step 4: Run the pphelper installer.
This will install the PP 5.0 tool. Click the installer to begin. When the installation finishes, click the “next” button to launch the PP 5.0.
Step 5: Download the PP 5.0 components.
These components are needed for the actual jailbreaking. Click the green button to begin the download.
