iPhone developer ih8sn0w has updated Sn0wbreeze to version 2.7 in-order to include support untethered jailbreak for iOS 4.3.3 (iPhone 4, 3GS, iPad, iPod touch) and iOS 4.2.8 on Verizon iPhone 4.
Step 1: First, download all the required tools and files to your Windows desktop:
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:
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).
