iPhone dev team had released Redsn0w 0.9.6rc13 earlier today which could not bring untethered jailbreak iOS 4.3.2 on iPhone 4. So the new Redsn0w 0.9.6 RC 14 is released specifically to address and make iPhone 4 compatible with untethered iOS 4.3.2 jailbreak exploit. Here we have a short Jailbreak How-To.
Requirements
Download iOS 4.3.2 for iPhone 4, 3GS, 3G, iPad, iPod touch
Download Redsn0w 0.9.6rc14 for Windows
Download Redsn0w 0.9.6rc14 for Mac
Download iTunes 10.2.2 for Windows or Mac
How to jailbreak iOS 4.3.2 using Redsn0w on Windows and Mac:
Step 1: Download iOS 4.3.2 for iPhone, iPad or iPod touch. (download links given at the bottom)
Step 2: Update/Restore to iOS 4.3.2 firmware using the IPSW file you just downloaded via iTunes 10.2.2.
Step 3: Start Redsn0w and point it to the official iOS 4.3.2 firmware file.
Step 4: Now select “Install Cydia” and click “Next”. Optionally (if available), you can also select any other option you like.
Step 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.
At this stage you will be presented with a screen where you will be guided on how to enter DFU mode. Quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.
Step 6: Sit back and enjoy while Redsn0w does the rest for you. Once done, your iPhone, iPad or iPod touch will restart automatically and you will find it fully jailbroken (untethered) on the latest iOS 4.3.2 firmware.
