Finally the jailbreak for iPad, iPhone and iPod Touch from the Dev Team is available for download. It’s free and untethered and it’s called “Spirit”. The jailbreak supports every iDevice with firmware version 3.1.2, 3.1.3 or 3.2.
If you have iPhone 3GS or an iPad you should backup your SHSH blobs before using the jailbreak. ECID SHSH or SHSH blob is a unique signature given to every Apple mobile device. When you decide to restore the firmware on your iPhone, iPod Touch or iPad, Apple servers checks this signature.
As you know, if a new firmware is released it becomes impossible to restore the older firmware from iTunes. But Cydia creator tuned up a new server and now it mimics Apple’s verification server and saves your older SHSH blobs so that you can restore back your device to the older firmware. Without having your SHSH blobs saved you may accidentally update new firmware and then you not only lose your jailbreak but also won’t be able to restore the older firmware to re-jailbreak your device.
This is also important because there is a big possibility that Apple will soon find out what exploit is used by the jailbreak and then it will be patched in the form of new firmware.
You can save your SHSH blob in three ways. Here is a guide to make it using AutoSHSH.
Start AutoSHSH and plug in you iPhone/iPod Touch/iPad in recovery mode (only one device at a time). Recovery mode launches when you turn off your device and hold down the “Home” button when connecting the USB cable. Then you must see “Connect to iTunes” message and logo on your device.
In AutoSHSH click on “Grab my SHSH Blobs Automatically”. When the app will grab the signature you must choose whether you want to save it locally or not. Do not forget where you saved the signature. In the end of the procedure AutoSHSH will also upload it to saurik’s server.
Please note that Spirit is not a carrier unlock so it won’t allow you to use unauthorized wireless carriers. The jailbreak is also “sort of beta”, so it may be buggy. DevTeam notifies that some apps in Cydia that are NOT designed for iPad may crash your system and require you to restore so be careful.
GeoHot recently posted a small message on twitter. He actually responds to many users who continue to ask him about the ability to run firmware 3.1.3 jailbreak using Blackra1n.
GeoHot has always been a bit reluctant to release new versions for various minor firmware updates. His advice is in fact once again to keep firmware 3.1.2, because the latest one does not have anything interesting.
GeoHot will be certainly back on the scene with the next release of firmware 3.2 in March / April or firmware 4.0 that is expected in July.
Fuzzyband is an application that can downgrade the baseband for iPhone 3G. Recently it has been updated to include the support for firmware 3.1.3 baseband 05.12.01. It works only with bootloader 05.08 (early iPhone 3G).
Why do users need to downgrade the baseband? The answer is simple: if they accidentally upgraded the new firmware and need to run unlocksoftware (blacksn0w and ultrasn0w). Unlocked iPhones do not need Fuzzyband. iPhone 3GS users cannot downgrade baseband with Fuzzyband.
Fuzzyband is available for jailbreaked iPhones in Cydia (repository BigBoss, category “System” ).
According to the statistics just 14% of iPhone users have updated the firmware to version 3.1.3.
In particular 72.3% are still using firmware 3.1.2, less than 1% – firmware 3.1.1 and 4.6% have previous versions yet. The reasons for this are probably from the fact that 3.1.3 is only a minor update. Another reason could be the uncertainty of the jailbreak.
The iPhone Dev-Team has released PwnageTool 3.1.5 for Mac OS X. It allows iPhone and iPod Touch users to safely upgrade to firmware 3.1.3. With PwnageTool you can preserve jailbreak and ultrasn0w unlock. But if you’re using the blacksn0w unlock with baseband 05.11.07 you will need to stay at firmware 3.1.2.
PwnageTool 3.1.5 creates a custom 3.1.3 IPSW for the following devices:
iPhone 3GS with early bootrom
iPod touch 1G
iPod touch 2G with early bootrom
Warning! Don’t try to use this tool if you have iPhone 3GS with firmware 3.1.3 – it just won’t work. If you have iPod Touch 1G, iPhone 2G or factory unlocked iPhone 3G , try to use redsn0w – is would be much easier.
H8sn0w has just released the new version of Sn0wbreeze 1.4. Sn0wbreeze is a jailbreak utility with functionality similar to PwnageTool. The new version supports firmware 3.1.3 jailbreak for the following devices:
Sn0wbreeze is a Windows application, so Mac users have to wait for the upcoming release of PwnageTool by the DevTeam. Alternatively, both Mac and Windows users can use Redsn0w to run jailbreak (no custom firmware though).
You can download the new version of sn0wbreeze here.
MuscleNerd continues to argue that we should not use sn0wbreeze. Especially users who have unlocked their iPhone with blacksn0w utility:
