Just a quick heads-up: redsn0w 0.9.6rc12 can jailbreak iOS 4.3.2 if you point it at iOS 4.3.1, but it’s a tethered jailbreak. If you don’t know how to use the tool, check out this redsn0w tutorial. NOTE: unlockers DO NOT update.
Apparently iOS 4.3.2 is still vulnerable to i0n1c’s untethered vulnerability so don’t be in a hurry to update. We will keep you updated, stay tuned…
