STEPS :
1. You need iOS 4.3.1 orignal ipsw file in order to jailbreak iOS 4.3.2
2. Open redsn0e 0.9.6rc12 and browse and open the orignal iOS 4.3.1
3. Start the process follow the on screen instructions in redsn0w

jailbreak iOS 4.3.2 using redsn0w 0.9.6rc12, by pointing it to iOS 4.3.1 firmware but it will still be TETHERED so you have to jailbreak it everytime you reboot your iPhone/iPad/iPod touch.
The update Apple issued for iOS 4.3.2 fixes bugs, FaceTime issues, and security issues. If you want to jailbreak iOS 4.3.2 I highly recommend you to stay on iOS 4.3.1 for now as its unclear whether or not iOS 4.3.2 patches the untethered vulnerability present in iOS 4.3.1.
Tethered means that whenever you want to reboot your device you must use redsn0w to use again your idevice with a working cydia. jailbreak iOS 4.3.2 using redsn0w 0.9.6rc12, by pointing it to iOS 4.3.1 firmware but it will still be TETHERED so you have to jailbreak it everytime you reboot your iPhone/iPad/iPod touch.
