Pangu

Pangu is a jailbreak program. It performs an untethered jailbreak for all devices on iOS 7.1.x, except the Apple TV. It was initially released on 23 June 2014, and became subject to controversy and criticism.

Controversy
Pangu installs 25PP, a Chinese cracked app store, if the user ticks the checkbox to install it. iH8sn0w confirmed that Pangu does not install spyware or phishing viruses onto the device.

Supported Devices
The only unsupported devices are those of the Apple TV family. All other devices capable of running iOS 7.1.x are supported.
