I received a tweet in my Twitter inbox around 2:15 AM PST from @iphone_dev and @ultrasn0w saying that PwnageTool, redsn0w, and ultrasn0w are updated to support 4.3.3 untethered.
The original exploit, found by @i0nic, was not patched when Apple released 4.3.3. However, there were some kernel crashes and other related issues that kept these above programs from rendering an untethered jailbreak. The team has finally fixed it and now it's hit the mainstream. All iDevices are supported with the exception of the iPad 2. For downloading the respective software, refer to the Dev-Team Blog and the following download links:
redsn0w for OSX
redsn0w for Windows
PwnageTool - Torrent
ultrasn0w can be found on Cydia. If you don't have the repository added (or accidentally deleted it), the repository is: repo666.ultrasn0w.com
redsn0w for Mac OSX can be confirmed as working for my device: iPhone 4 GSM 32 GB v4.3.3
***UPDATE*** sn0wbreeze has been updated to support 4.3.3 untethered along with 4.2.8 on Verizon as well.
