This is just a quick warning for all of you unlockers and jailbreakers out there. MuscleNerd has just tweeted that if you rely on an unlock you should stay away from iOS 4.3.1 firmware update as it is not safe. Also included in MuscleNerd’s tweet was a warning for future iPad 2 jailbreakers. If you plan on jailbreaking your iPad 2 in the near future do not press the update button or you could be left out when an untethered iOS 4.3.1 jailbreak is released. Apple has patched all possible exploits in this firmware update. Have a look at the Musclenerd's tweet below.



You can note that MuscleNerd also warn iPad 2 jailbreakers to stay away from updating to iOS 4.3.1 just to be extra safe at least for now. If you ask about unlock for iPhone 4, you may like to check out Gevey SIM unlock. We will keep you updated on the situation until then please stay tuned
