Since Stefan Esser uncovered a new iOS 4.3.1 exploit earlier this week, the Dev Team has been working double shifts to include the method in both PwnageTool and redsn0w. Earlier today, the team finally confirmed that updated versions of their tools will be released late tonight, at 12 AM Pacific Time. As usual, the new version of PwnageTool will be compatible with Macs only, while redn0w will be compatible with both Macs and PCs. Note that folks looking to keep their unlocked baseband will prefer PwnageTool over redsn0w. The new jailbreaks will be compatible with all devices running iOS 4.3.1, namely iPhone 3GS and iPhone 4, third and fourth generation iPod touch, and last but not least, first generation iPad. iPad 2 users will need to be patient, as at this stage, the device proved to be immune to all known jailbreak methods. Once the tools are released, make sure to fully backup your device (including your SHSH blobs via a tool such as TinyUmbrella), just in case. As always, even though jailbreaking is considered legal, always keep in mind that Apple sees it as a warranty-voiding act, so do it at your own risk. Please do not use jailbreaks to install copyrighted/paid content you haven’t purchased yourself.
