Sund0wn is a downgrade utility which allows tether and untether downgroades for iOS 6.0-7.1.2 for the iPhone 4. It is for the Windows family of operating systems written by iSuns9. It works on all iPhone 4 models. This is useful if you want to use older iOS versions. Even if Apple doesn't sign that firmware anymore, sund0wn creates a restoreable IPSW so that you can install the firmware and tether boot after.
