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. » PwnageTool & Ultrasn0w Updated For iOS 4.3.2 [jailbreak]

MuscleNerd just announced that ‘ The 4.3.1 issues (signal bars, etc) are fixed, but need a few days to test all devices + FW (again: not a new unlock! ) ‘ . This won’t be a brand new ultrasn0w, but an update to the existing one which will allow already unlocked iPhone users to update to iOS 4.3.1. » Ultrasn0w For iOS 4.3.1 To Be Released In A Few Days
