iH8Sn0w released Sn0wBreeze 2.9.10 that brings support for untethered jailbreak of iOS 6.1.2. New version supports iPhone 3GS, iPhone 4 and iPod Touch 4G. It does not work with A5/A6 devices, like iPad 2, iPad 3, iPhone 4S, iPhone 5, etc.
Sn0wbreeze can be used to create a custom firmware with jailbreak and preserve iPhone modem (baseband) version for unlock. It can also be used to upgrade iPhone 3GS modem version to 06.15.
You can find the release notes below. You can download the latest version of Sn0wBreeze from here.
This step-by-step tutorial will guide you through the process of full restore, that is highly recommended for iOS 6.1 jailbreak. You can use this tutorial for any iPhone, iPod Touch and iPad.
Important: do not update to iOS 6.1 if you need carrier unlock.
Step 1
Make a folder called “Firmware”. Download iOS 6.1 for your Apple device:here.
iH8Sn0w released Sn0wBreeze 2.9.7 that brings support for tethered jailbreak of iOS 6.0.1. New version supports iPhone 3GS, iPhone 4 and iPod Touch 4G. It does not work with A5/A6 devices, like iPad 2, iPad 3, iPhone 4S, iPhone 5, etc.

What is New?
● Added 6.0 (10A403)/6.0.1 (10A523) support. (Only includes iPhone 3GS & A4 devices).
● The 6.0/6.0.1 is currently a tethered based jailbreak via iBooty (except for iPhone 3GS old bootrom users).
● SAM is built-in for iOS 6 hacktivations. (Hacktivated phones can reboot to a semi-tethered state after being activated [rather than just hang at the Apple Logo]). Kudos @sbingner!
Downgrading:
● Use iFaith mode after selecting/downloading the appropriate IPSW for your device. You will then be prompted to browse for SHSH blobs for the IPSW you have selected.
● Remember to enter a PWNED DFU state with sn0wbreeze’s iREB button in the top bar of sn0wbreeze prior to (SHIFT + Restoring) the custom signed IPSW!
iREB & iOS 6:
Due to some changes in iOS 6, the current public standalone version of iREB will NOT enter a proper PWNED DFU state for restoring to custom iOS 6 IPSWs. An update for the standalone version should come sometime this week. In the meantime, use the iREB tab located in sn0wbreeze’s top status bar to enter a proper PWNED DFU state.
A5(X)/A6(X) Support?:
As stated many times in the past, sn0wbreeze cannot be updated to work on A5(X)/A6(X) devices until a low level exploit in DFU or iBoot is found and made public.
A5(X)/A6(X) Baseband Preservation/Hacktivation?
For those running A5(X)/A6(X) devices and need to preserve your baseband, there is nothing you can do at the moment. For those wanting to hacktivate, the only advice I can give is to buy the carrier’s SIM (the one its locked to obviously) on ebay. The SIM does not have to be active with the carrier to activate the phone.
Known Bugs/Issues:
● Windows 8 users currently need to use this workaround to run sn0wbreeze.
● iPad baseband will fail to flash on iOS 4.0 –> iOS 4.2.1 restores.
● iPod Touch 2G 4.x.x restores fail.
The iPhone Dev-Team released RedSn0w 0.9.14b2 with improved algorithm for baseband downgrade from the iPad’s 06.15 baseband to 05.13 on the iPhone 3GS and iPhone 3G. The 06.15 baseband was used by many users to unlock their device. Now it is possible to to get back true GPS and an ultrasn0w unlock.
Typically you’d have the 06.15 baseband if you unlock with ultrasn0w but updated your iPhone baseband past 05.13.04. With this new capability, you can now downgrade specifically from 06.15 to 05.13.04 (even if you never had 05.13.04 on that device before). This gives you the best of both worlds: ultrasn0w compatibility and a normal iPhone baseband with full GPS and the ability to use stock IPSWs again.
The revised steps are:
Connect your iPhone in normal mode, then click “Jailbreak” after redsn0w identifies its model and BB version (you needn’t pre-select the IPSW anymore).
Choose the “Downgrade from iPad baseband” option (you needn’t worry about de-selecting Cydia anymore).
Do a controlled “slide to power off” shutdown of your phone and proceed through the normal DFU ramdisk steps.
After the ramdisk gets launched and you see the Pwnapple running on your iPhone, you’ll eventually get to the “Flashing Baseband” step. THIS STEP TAKES A VERY LONG TIME to complete and there won’t be any feedback while its running. Please just let it be for the next 3-8 minutes! When the ramdisk has done its job it will reboot the phone on its own.
For those who are wondering if you can update your 3G or 3GS to 06.15 solely for the purposes of downgrading to 05.13.04, the answer is “yes” for 3G owners, and “maybe” for 3GS owners. The iPad baseband is not compatible with 3GS units manufactured week 34 of 2011 or later. If you have an iPhone3GS and if digits 3-5 of its Serial Number are 134 or later (xx134…), then you should NOT try to install the 06.15 baseband on your 3GS! It will brick your radio, preventing both the downgrade from working and normal iPhone software from using it as a phone! Be warned!
Update #1: If you’re still using ultrasn0w after going down to 05.13.04, many people have reported that re-installing Mobile Substrate and/or ultrasn0w fixes crashes and “No Signal”.
The iPhone Dev-Team released RedSn0w 0.9.14b1 that can perform a baseband downgrade from the iPad’s 06.15 baseband to 05.13 on the iPhone 3GS and iPhone 3G. The 06.15 baseband was used by many users to unlock their device. Now it is possible to to get back true GPS and an ultrasn0w unlock.

This gives you the best of both worlds: ultrasn0w compatibility and a normal iPhone baseband with full GPS and the ability to use stock IPSWs again.
Here are the steps:
Use the “Extras->Select IPSW” button in redsn0w to tell it which firmware version you have installed (new-bootrom 3GS users can usually skip this step but it doesn’t hurt for them to do it too).
Do a controlled shutdown of your iPhone (“slide to power off”). This step is very important to avoid mount problems when the ramdisk is running!
Go back to the first screen and click “Jailbreak”. Enable the “Downgrade from iPad baseband” checkbox, disable Cydia if you already have it installed, and click Next to proceed through the normal DFU ramdisk steps.
After the ramdisk gets launched and you see the Pwnapple running on your iPhone, you’ll eventually get to the “Flashing Baseband” step.
