Geeksn0w is a jailbreak program that currently performs a tethered jailbreak for the iPhone 4 on iOS 7.1.

Supported Devices and Requirements

The only supported devices are those of the iPhone 4. This is because Geeksn0w uses opensn0w and geohot's limera1n exploit which is only available for A4-based devices and the iPhone 4 is the only A4 device that runs iOS 7. Geeksn0w currently only supports Windows. Geeksn0w requires Java Development Kit for 32-bit PCs and .NET Framework installed on your computer to be able to run. Unlike other jailbreak tools such as evasi0n7, Geeksn0w does not need iTunes to be installed.

Versions and Updates

• Geeksn0w originally performed an tethered jailbreak on iOS 7.0 on the iPhone 4 until evasi0n7 was released. BlackGeek then updated Geeksn0w to use the same exploits as evasi0n7 for all devices. Versions 2.5 and above perform a tethered jailbreak on iOS 7.1 for the iPhone 4.

How it works

Geeksn0w uses msftguy and DevBug's SSH RamDisk tool which uses and geohot's limera1n exploit to obtain root access. It then installs Cydia and mounts the root filesystem. It then uses opensn0w to boot the iPhone 4 tethered. Geeksn0w is technically a GUI of opensn0w and ssh_rd.
