How to Jailbreak iOS 4.3 with Sn0wBreeze 2.3 Beta [Tethered] [Windows]

In case you could not resist upgrading to Apple’s latest firmware release iOS 4.3 or your device shipped with iOS 4.3 installed, iH8sn0w does have a solution to Jailbreak iOS 4.3. However, the beta app only works in Windows and does a tethered jailbreak on iPhone 3GS, iPhone 4, iPod Touch and the iPad first generation. Full instructions after the break.

In case you haven’t upgraded to iOS 4.3 yet, make sure you read the previous post Should I Upgrade my iPhone to iOS 4.3?

Once again, let me repeat that this is a beta app and might not perform as well as your previous jailbreak. Secondly, since this is a tethered jailbreak you will have to boot tethered using your computer, everytime the iOS device restarts. Ultrasn0w unlockers beware, you cannot unlock carrier on iOS 4.3 yet.
