0.9.6rc12 (Windows, ) is capable of performing a tethered of .2 if pointed to the firmware, according to MuscleNerd.
last week’s redsn0w can JB 4.3.2 (if you point it at 4.3.1 IPSW) but that’s a tethered JB (doesn’t imply anything about @i0n1c’s untether)
We are still waiting for news on the status of an untether. In the meanwhile, if you must update, make sure to save (Windows, Mac) your SHSH Blobs then use one of the following tutorials to jailbreak skipping the part where you restore to 4.3.1.
