Recently iOS 4.3.2 has recently been found to be vulnerable to the 4.3.1 untethered jailbreak exploit. What this basically means is that you can use Redsn0w 0.9.6rc12 to jailbreak iOS 4.3.2! The only downside is that it is tethered right now, but don’t worry, the untethered jailbreak will be released soon (i0nic is busy this weekend and cannot recompile the binaries for 4.3.2).
Here is what you need to do to jailbreak iOS 4.3.2 using Redsn0w, you will need:
1. A iDevice running 4.3.2 (This doesn’t work on the iPad 2, or the Verizon iPhone I believe)
2. Your firmware file for 4.3.1
3. Redsn0w 0.9.6rc12
4. Your SHSH blobs saved for 4.3.1 (This is optional, but you might want to have them saved while you still can!)
You need to open redsn0w (On Windows 7 / Vista make sure you “Run As Administrator” and the compatibility set to Windows XP Service Pack 3) . When it asks you for your firmware file make sure you choose the 4.3.1 firmware file (We need to do this to trick Redsn0w into using the correct jailbreak, it doesn’t recognize the 4.3.2 firmware yet because when rc12 was made, there was no 4.3.2). Then run the jailbreak as normal, but when it is finished, you will need to reopen Redsn0w (same thing as earlier, run as admin, and with XP compatibility) and this time when you get to the options check the box “Just boot tethered right now”, it should automatically uncheck all of the other boxes for you. Now continue on and it should boot you up and you can use Safari / Cydia on your jailbroken iOS 4.3.2 device! Enjoy!!
