As we know Apple has released the iOS 4.3.4 yesterday to kill the Comex PDF exploit which was uses by JailbreakMe 3.0 to jailbreak the iPad 2 and all other iOS devices running on iOS 4.3.3, using their Mobile Safari. So jailbreak hackers has warned users not to update their iOS devices to the latest version because Apple has also killed the i0n1c untethered exploit which is currently uses by iPhone Dev team software, Redsn0w and PwnageTool. But as we know Limera1n of Geohot is still present in all iOS version because its kernel based exploit which can only fix by hardware change. MuscleNerd of iPhone Dev Team has just announced the new beta version of Redsn0w 0.9.8b3 to provide tethered jailbreak on iOS devices running iOS 4.3.4 and also warns other users not to update their device until they don’t discover or hack the iOS version again for untethered jailbreak.
iPhone Dev Team:
Update #3: For the convenience of kernel hackers like @comex and @i0n1c, we have a new redsn0w 0.9.8b3 that supports a TETHERED jailbreak for iOS 4.3.4 on all devices that have 4.3.4 except the iPad2. The vast majority of people will want to stay back at 4.3.3 because that’s where the untethered jailbreak is! There are no new features in 4.3.4 — only fixes for jailbreak exploits.
Also, this is a good time to remind everyone (since we’re still seeing confusion about this): iPad2 owners with a baseband (3G or CDMA) cannot currently use saved blobs to go back to 4.3.3 once the signing window is closed. This is unlike every other device, so don’t be confused! iPad2 owners with basebands should stay away from all updates to maintain the jailbreak!
Jailbreaking procedure is similar to the previous iOS versions, all you need to do is download the latest jailbreak tool and stock iPSW of iOS version and perform magic on it, for deep information we have already cover the iOS jailbreak tutorial just head over to it.
