Resident jailbreak expert Reza is ready to help you upgrade your current jailbreak for 4.3.1. The untethered jailbreak tools for iOS are ready and in the wild. If you’ve been waiting to upgrade your jailbroken iPad, iPod touch or iPhone, you can grab several of the new features by grabbing 4.3.1.
redsn0w is one of the tools you can use to perform your upgrade – or new jailbreak. redsn0w is a multi-platform jailbreak and unlock tool created by the iPhone Dev Team. redsn0w is simple to use, and supports all current iPhone and iPod touch devices which use at least firmware 3.0.
ultrasn0w is another tool that can be used to accomplish the same task. This unlock will work on iPhone4 baseband 01.59 and 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04. If you have trouble finding ultrasn0w within Cydia, add this repo: repo666.ultrasn0w.com.
So why would you want to unlock your device to begin with? Many people enjoy the Apple hardware but prefer a more open software experience. They want to change the way things are done on their iDevice and even add some functionality that may not have already been there. It’s important to note that doing this is NOT illegal, but it does void your Apple warranty. You should always unlock or jailbreak at your own risk, and realize that no one can be held liable if you receive less-than-desirable results.
If you have an unlocked iPhone, you’re going to want to stay away from doing a straight upgrade. There are alternate update methods you can find in order to help you do some custom patching of the iOS before updating. Or, you can also use Tiny Umbrella to block your baseband and allow this upgrade.
If you’re ready to upgrade, 4.3.1 is great due to the hotspot features alone. It allows you to share your 3G signal with your iPad and other devices. With the iPad, it’s super cool because the GPS functionality from your phone will carry over into your iPad.
