Sn0wbreeze 2.7 Supported devices include:

* iPhone 4 (GSM)
* iPhone 4, iOS 4.2.8 (Verizon)
* iPhone 3G
* IPad
* IPod touch 3G
* IPod touch 4G


Step 1: First, download all the required tools and files to your Windows desktop:

• Download and install iTunes 10.2.2 for Windows.
• Download sn0wbreeze 2.7 for Windows.
• Download iOS 4.3.3 for iPhone, iPad or iPod touch.
• Download iOS 4.2.8 for Verizon iPhone 4.

Step 2: Start Sn0wbreeze, click the next “blue” colored arrow to proceed.


Step 3: Select the required firmware .ipsw file (iOS 4.2.8 for Verizon iPhone 4, or iOS 4.3.3 for GSM iPhone, iPad & iPod touch) for your iOS device by clicking on the “Browse” button.


Step 4: Sn0wbreeze will now identify the selected IPSW file. Once done, click the next “blue” colored arrow to proceed.


Step 5: Now select the “Expert Mode”, followed by “Build IPSW” option to start creating your custom firmware.


Since building custom firmware may take some time, you can optionally play Pac-Man game to kill some time.


Step 6: Sn0wbreeze will greet you with the following “Done!” message when the custom firmware has been successfully created.


Step 7: Now follow the onscreen steps to enter DFU mode using Sn0wbreeze:

• Hold Power and Home buttons for 10 seconds
• Now release the Power button but continue holding the Home button for 10 more seconds
• You device should now be in DFU mode

If you have followed the steps correctly, you will get the following message from Snw0breeze


Step 8: Start iTunes, click on your iOS device icon from the sidebar in iTunes. Now press and hold Left “Shift” button on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in iTunes and then release this button.
This will make iTunes prompt you to select the location for your custom firmware 4.2.8 (for Verizon iPhone 4), or 4.3.3 (for GSM iPhone, iPad & iPod touch) file. Select the required custom .ipsw file that you created above, and click on “Open”.


Step 9: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 4.2.8 (for Verizon iPhone 4), or 4.3.3 (for GSM iPhone, iPad & iPod touch) on your iOS device. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your iOS device will be jailbroken on 4.2.8 (for Verizon iPhone 4), or 4.3.3 (for GSM iPhone, iPad & iPod touch).

Is this tethered or untethered? I am on 4.2.7 I really want to wait till greenposiOn comes out. It just seems easier than RedsnOw. I am new to Jailbreaking. Untethered means you can reboot the phone without a computer, yes?

Yes, untethered means that you can reboot your iPhone and still use all of the jailbreak apps.

The redsn0w untethered jailbreak is no more difficult than greenp0ison. I'm no jailbreaking expert. All I do is follow the directions the fine people post here and it works. Even if you screw up the jailbreak, you always can bail out with the iTunes restore and start over. I goofed up the process and my phone was dead in the water but reconnected the usb, restarted iTunes, restored out of box and redid the jailbreak and worked perfectly fine. It''s practically foolproof.

I'm trying to upgrade from 4.2.6 to 4.2.8 and i'm getting the error message that says IPSW file is not valid. I've downloaded this file afew times and still can't do it. Again, Any assistance will greatly appreciated.

I followed all the steps to JB 4.2.8. I went all the way to restore on iTunes but I don't have cydia anywhere on my phone. Not sure what went wrong can someone please point me in the right direction to get my JB going again? Or is it just as easy to go thru the whole process again? Thanks in advance.

Are you dragging the zip file into the window where it asks "drag the ipsw into me?"

Once it gets going, at some point, the actual .ipsw file will be created on the desktop which you will need later on during the jailbreak process.
