Yesterday, we reported on how iOS 4.3.4 won’t be receiving an untethered jailbreak from the hacking community anytime soon. i0n1c’s old exploit that was used to jailbreak iOS 4.3.x has been patched by Apple and new details have emerged regarding the patching of said exploit.
If you've been paying attention to the news lately, and especially to this website, you know how much we've covered iOS 4.3.4, Apple's emergency security update for iPod touches, iPhones and iPads. If you're still thinking about installing it, there's yet another reason you shouldn't if you're using an iPad 2: you can say goodbye to jailbreaking it altogether, at least until a new hack is found.
Earlier today, Apple released iOS 4.3.4 to close the PDF jailbreak hole which was exposed by Comex’s JailbreakMe 3.0. We have already warned you NOT to update to 4.3.4 if you want to keep your untethered jailbreak. If you updated by mistake, you can downgrade back to 4.3.3 and enjoy full untethered jailbreak as long as you have saved SHSH blobs for the firmware you are downgrading on.
Apple has just pushed out iOS 4.3.4 for the iPhone, iPad and the iPod touch. And thankfully, we have cooked custom PwnageTool bundles which allows you to jailbreak any device (except for iPad 2) running iOS 4.3.4, and at the same time preserve your baseband for an Ultrasn0w unlock later on.
