Redsn0w

redsn0w 0.9.5-b5

redsn0w was originally called QuickPwn but due to the theft and exploitation of the name, QuickPWN by quickpwn.com, as of iOS 3.0, QuickPwn was discontinued and redsn0w (at the time, version 0.7) was converted into a jailbreaking tool for all current devices as well as providing unlock support the iPhone 2G. As of version 0.8, the iPhone 3GS can also be jailbroken through redsn0w.

Version 0.9 beta 3 was released for Windows and Mac OS X, and it allows iOS 3.0 through 3.1.2 to be jailbroken. It includes support for all devices except the iPod touch 3G, and supports a tethered jailbreak on iPhone 3GS units and iPod touch 2G units with new bootroms. In addition, this version supported custom boot and recovery mode logos, as well as verbose mode on bootup.

The final release, version 0.9.2, supports jailbreaking of all iDevices (at the time) with iOS 3.0 through 3.1.2 on Windows and Mac OS X, as well as 3.1.3 on S5L8900 devices. Version 0.9.3 adds support of internet tethering IPCC hack on those devices and 0.9.4 allows jailbreaking of early iPod touch 2G with iOS 3.1.3.

Version 0.9.5b5-5 supports jailbreaking the iPhone 3G and iPod touch 2G (old bootrom) with iOS 4.0 on Windows and Mac OS X.

redsn0w 0.9.6b1 supports jailbreaking the iPhone 3G and iPod touch 2G (both bootroms, although the new bootrom's jailbreak is tethered) with iOS 4.0 through 4.1 on Mac OS X and Windows.

This button (which you can use from Windows) lets you prepare your device for a custom DFU. Even if you’re purely a Windows user, you can get a trusted friend to run PwnageTool over your IPSW to create a custom IPSW. You can now install that custom IPSW on your own Windows box, after you run this redsn0w version.
