Recently, Apple has released the new iOS firmware 4.3.4. This is to combat the PDF vulnerability uncovered in the latest version of JailbreakME. In less than a day, The Dev Team has also released the jailbreak through RedSn0w 0.9.8b3, an updated version in which it will provide a TETHERED jailbreak.
When you have jailbroken your iDevice running iOS 4.3.3, especially an iPad 2, DO NOT update your iOS to 4.3.4 since there is no more a possibility to have an untethered jailbreak for that firmware.
It will be impossible for iPad 2 running iOS 4.3.4 to jailbreak using the latest version of RedSn0w, so you really should stay with 4.3.3 and jailbreak using JailbreakME 3.0. If you have jailbroken your iPhone 4 already, just don’t do anything and remember to stay away from updates. This is because Apple intentionally released iOS 4.3.4 in order to combat the exploit used by JailbreakME 3.0 so updating your iDevice is unnecessary. Back up your SHSH blobs as soon as possible in order to avoid inconvenience whenever accidental updates will occur.
The most convenient way to jailbreak your iPhone 4 running iOS 4.3.3 is by JailbreakME 3.0. The tool is so easy and simple to use and you don’t even need a computer to do it. Safari browser is all what you need to do it. To remain secured after jailbreaking with JailbreakME 3.0, install PDF Patcher 2 available in Cydia.
Remember that the jailbreak using the latest RedSn0w for iOS 4.3.4 is a TETHERED one. This means that you need to jailbreak again every time your iPhone has rebooted or drains out of battery.
My next post will be a step by step guide on how to jailbreak your iPhone using RedSn0w. This is to help anyone who may have accidentally updated to iOS 4.3.4. In the meantime, we’ll wait and hope for the good news that the jailbreak community may come up.
