Only a few weeks after the 4.3.1 untether created by @i0n1c was released, Apple pushed out firmware 4.3.2. Thankfully, it appears Apple didn’t have a chance to fix the hole used by @i0n1c’s untether, so he ported his code over to 4.3.2’s kernel. Today’s redsn0w has been updated to include it.
The 4.3.2 untether works on all devices that actually support 4.3.2 except for the iPad2:
iPod touch 3G
iPod touch 4G
OS X redsn0w
As always, ultrasn0w unlockers should stay away from redsn0w and only update their firmware through a custom IPSW. We’ll release a new version of PwnageTool sometime this week.

Update #2: redsn0w rc14 includes the fixed i4 untether from @i0n1c. You can re-run redsn0w rc14 right over the tethered rc13b to transform the i4 JB into an untethered one.
