How to Jailbreak iPhone 3G | iPod Touch 3G | Untethered Jailbreak 3.1.3

The untethered Jailbreak for iPhone 3G 3.1.3 and iPod Touch 3G 3.1.3 has arrived. After much anticipation, the new tool makes jailbreaking of iPhone 3G and iPod Touch 3G possible. Earlier, the new 3.1.3 firmware update by Apple had disabled all jailbreaks on the new 3G devices.

Although, ProgrammingKid had brought the Downgrade Guide from 3.1.3 to 3.1.2 for all users who had accidentally upgraded to 3.1.3. The jailbreak from BlackRaIn by Gehot was tethered.

What is untethered Jailbreak?

If you have one of the newer iPod touch 3rd-gen, or iPod touch 2G (2nd-gen), which came with iPhone OS 3.1.3 as pre-installed. If you have ever tried jailbreaking this model, you would know how annoying it is to greet with that “Connect to iTunes” screen every time you restart it. This is because it was jailbroken using tethered jailbreak method.

But now with Spirit, you can jailbreak your device as untethered, which effectively means that you are no longer required to re-jailbreak your iPhone or iPod touch every time you restart it.

Features of Spirit for Jailbreaking iPhone 3G, iPod Touch 3G

According to the developer of Spirit,

Spirit is an untethered jailbreak for iPad, iPhone, and iPod touch on the latest firmwares.
Spirit is not a carrier unlock.
If you currently are using a tethered jailbreak, you have to restore to use Spirit. Do not upgrade if you use an unlock on an iPhone 3G or 3GS. (You can, however, restore to 3.1.2 if you have SHSH blobs for that version.)
