iOS 4.3.4 Already Jailbroken
On Friday, Apple launched iOS 4.3.4 to patch a vulnerability that allowed hackers to remotely take over iOS devices. Unfortunately, this security risk was also the same PDF exploit used by Comex to release JailbreakMe 3.0 a little over a week ago. Not a big deal if you stuck with iOS 4.3.3, but for those of you who didn't get the memo, there is a savior in the form of a tethered jailbreak. Not as good, but better than nothing.
Redmond Pie released a tutorial on how to jailbreak your iPhone, iPad (sorry doesn't work for the iPad 2) and iPod touch running iOS 4.3.4.
You’ll need PwnageTool 4.3.3, iOS 4.3.4 firmware, iTunes 10.3.1, Mac OS X, PwnageTool bundles for iOS 4.3.4 and tetheredboot utility. You can get all these and directions on how to use them by visiting Redmond Pie.
