Update 1: I think there's no need for Custom Firmwares anymore! Comex has released his new userland jailbreak "JailbreakMe 2.0" Star, you can find our guides and full coverage posted here.

Last week, George Hotz a.k.a Geohot has left the Jailbreak scene but he may be back soon according to his Friend Mike. Whatever today we have another developer is leaving the Jailbreak scene too! Our lovely iH8sn0w the developer behind Sn0wbreeze, F0recast and AutoSHSH has closed his Site for some reasons mentioned below..

Well, I respect this guy a lot and my message to him is not to leave as he is genius and we all respect him and his tools! The reason behind leaving is because Jay Freeman a.k.a saurik the developer of Cydia who said that iH8sn0w is not "Legit", meanwell people can't trust iH8sn0w?
iH8sn0w already developed nice tools but he failed in some guides and corrected his mistakes! he created some advanced guides to jailbreak iPod touch 3G and iPhone 3GS new boot who got 3.1.2 SHSH. So Dude, What about not leaving and prove your Self with a new Sn0wbreeze! Oh and remember iPhone 4 will be delivered in Canda by July 30 so get your self ready!

Update 1: Guys, it was just a mistake as iH8sn0w said that pie was a joke and he is not a source of news -- That's why saurik said he is not "Legit" but at Last saurik apologized or making him sound deceiving, Sure the site will be back soon! will tell you on Twitter.

Update 2: The two official sites for iH8sn0w this & this has been restored again .

According to FSM, iH8sn0w is now in work on a new update for Sn0wbreeze, he mentioned that Sn0wbreeze 2 is in Making for iOS 3.1.x / iOS 4.0 / iOS 4.0.1 and iOS 4.1 beta 1. This new update for Snm0wbreeze will support all devices except iPad and iPhone  4 as iH8sn0w didn't get a one yet!

Notes:
- For iPod Touch 2G (MC Model) you don't need to have 3.1.2 SHSH Blobs
- For iPod Touch 3G / iPhone 3GS you need to have 3.1.2 SHSH Blobs NOT 3.1.3
- This is tethered jailbreak, which means that you have to Reconnect your device with computer whenever it's turned off to turn it on

Steps:

I figured making a tool would take a bit too long. So, i'm going to write up this tutorial. It isn't recommended for regular users.

**BEFORE PROCEEDING, ENSURE THAT YOU HAVE YOUR iPod/PHONE BACKED UP!**

THIS TUTORIAL ASSUMES YOU ARE ALREADY ON 3.1.2!

Q: Why not 3.1.3???
A: The exploit used is closed in 3.1.3 and beyond.
-------
WHAT YOU WILL NEED:

* An iPhone 3G[S] or iPod Touch 2G MC or iPod Touch 3-- new bootrom
* 3.1.2 already installed or 3.1.2 installed via SHStarget="_blank"H blobs. <-- Broken blackra1n'd devices will work. (Especially if Spirit messed you up!).
* Payload Pwner-r6
* sn0wbreeze V1.7
* iBooty V1.6
* 3.1.2/4.0 firmware downloaded.
* iTunes 9.2 Installed
-------
STEP A : Pwning iBoot
I : Download this easy tool here -- Payload Pwner-r6 // It will help you create the payload.
II : Extract it to a directory and run Pwner.exe
target="_blank"
**SAVE THE PAYLOAD WHERE iBooty is.**
-------
STEP B : Making a Custom IPSW
I : Download sn0wbreeze V1.7 from here -- sn0wbreeze V1.7
II : USE EXPERT MODE!
III : In General, Checkmark "Disable NOR Flash" <-- THIS IS ESSENTIAL!!!!
IV : Build it. It will be on your Desktop.

**CUSTOM BOOT LOGOS THAT ARE MADE IN sn0wbreeze WILL NOT WORK ON NEW BOOTROMS!**
*Mac Users : PwnageTool does not have this option. I don't think it will ever be in there. Use a Windows Virtual Machine or friends PC to create your firmware.*
-------
STEP C: iBooty Prep.
Most of you know of the utility "iBooty" that I made for Aki_nG.
It will work as long as you place all of the correct files there.
I : Download iBooty GUI here -- iBooty V1.6 and Extract it.
II : Extract your Custom IPSW created by sn0wbreeze with 7-Zip or another un-archiver.
III : Grab the kernelcache and bring it into the same folder as ibooty.
Also grab iBEC from the folder "Firmware\dfu".
Aswell as DeviceTree from the folder "Firmware\all_flash\all_flash.n88ap.production\DeviceTree.n88ap".
IV :
* Rename your Kernel 4.0-Custom to "kernel.40"
* Rename your iBEC 4.0-Custom to "ibec.40"
* Rename your DeviceTree 4.0-Custom to "devtree.40"
***MAKE SURE YOU REMOVE THE .img3/.dfu/etc extensions!***
======
Your folder should look like this :
- iboot.payload <-- Created with Payload Pwner.
- devtree.40 <-- Grabbed from Custom IPSW made by sn0wbreeze.
- ibec.40 <-- Created with Payload Pwner.
- bspatch.exe <-- Comes with iBooty.
- iBooty.exe <-- Comes with iBooty.
- kernel.40 <-- Grab from Custom IPSW made by sn0wbreeze.
- sn0w.img3 <-- Comes with iBooty.
- wait.img3 <-- Comes with iBooty.
======
-------
STEP D: Restoring to 4.0 + Booting
-------
*MAKE SURE YOU ARE ON 3.1.2 WHEN DOING THIS*
I : Run iBooty and Select "Prepare Device for Custom Firmware". Run the Process and if you see the image, you can proceed!
II : Now open iTunes and restore to the custom ipsw.

***WHEN DONE, YOUR DEVICE WILL GO INTO RECOVERY MODE. IT WONT BOOT.***
-------
STEP E : Booting
I : Just Re-Run iBooty and select "Boot It". If all goes well it will boot!

Here's a video to See it in action, credits for iH8sn0w:
