The iPhone-Dev Team have just updated their jailbreak tool RedSn0w 0.9.6rc15 to jailbreak iOS 4.3.3 untethered. It is based on i0nic’s untethered jailbreak exploit that can also jailbreak iOS 4.3.1 and 4.3.2 untethered.

This jailbreak exploit uses Geohot’s bootrom exploit to inject the jailbreak. RedSn0w 0.9.6rc15 works on all devices that actually supports iOS 4.3.3 except for the iPad 2:

• iPhone3GS
• iPhone4 (GSM)
• iPod touch 3G
• iPod touch 4G
• iPad1
• AppleTV2G (v4.3 8F202)

Important: If you want to preserve your unlock, then this method is NOT for you. To maintain your baseband you need to create custom IPSW files and PwnageTool. iPhone unlockers must use Sn0wbreeze 2.6.2 and PwnageTool 4.3.3 to create custom firmware and then unlock their device using UltraSn0w 1.2.4.

Things required during Jailbreaking process:

• iOS 4.3.3 IPSW firmware file
• RedSn0w 0.9.6rc15
• iTunes 10.2.2

Steps to Jailbreak iOS 4.3.3:

1. Update and Restore iOS 4.3.3 firmware using IPSW files that you have just downloaded.

2. Start RedSn0w 0.9.6rc15 and point it to the official iOS 4.3.3 firmware file.

3. Select “Install Cydia” and enable “Multi Task Gestures”.

4. Make sure that your device is both powered OFF and PLUGGED IN to the computer before you click on “Next” button.

5. Now you have to put your device into DFU mode. To enter into DFU mode simply follow the following steps:

• Press and hold the Power and Home button simultaneously for 10 seconds.
• Now release the Home button but continue holding the Power button for another 10-15 seconds.

6. When your device successfully enters into DFU mode, RedSn0w will now start jailbreaking iOS 4.3.3 untethered.

7. Your i-device will restart automatically and you will find it fully jailbroken on iOS 4.3.3 firmware.
