This Sunday, the latest untethered jailbreak for iOS 4.3.1 was released by the Dev-Team. Here we are, with the complete guide to jailbreak your iPhone 4 or iPhone 3G using Redsn0w.
The Dev-Team has also updated PwnageTool for Mac to jailbreak iOS 4.3.1 but Redsn0w is not only available to both Windows and Mac users but also offers a faster jailbreak process since it does not require any custom IPSW to be created.
This guide can also be used to jailbreak the iPod Touch 4G and 3G and the iPad first generation. If you were putting off the update to iOS 4.3.1 on your device, due to the lack of a stable untethered jailbreak solution, your wait is now over.
Important Note: Read before Jailbreaking
If your iPhone is not factory unlocked and you use Ultrasn0w on your iPhone 4 or iPhone 3GS then please note that Ultrasn0w does not work with iOS 4.3.1 at the moment. The Dev-Team will be releasing an updated Ultrasn0w in Cydia soon.
Also, you must not update your iPhone with stock firmware from Apple. In order to preserve the iPhone baseband, upgrade to iOS 4.3.1 using custom IPSW created in PwnageTool or by using TinyUmbrella only.
Preparing for iOS 4.3.1 Jailbreak:
You must first download Redsn0w and the iOS 4.3.1 firmware in order to proceed with the jailbreak. Here are the links:

Since, RedSn0w does not create any custom IPSW you need to update your iPhone to iOS 4.3.1 before performing the jailbreak.
Launch iTunes and connect your iPhone using the dock connector to USB cable. Now press Alt key on your Mac’s keyboard and click on Check for update. Windows users need to press the Shift key and then click on update.
You can now select the IPSW file downloaded in the previous step to update your iPhone. In less than ten minutes, your iPhone will update and reboot.
We are now ready to proceed with iOS 4.3.1 jailbreak.
Instructions to Jailbreak iOS 4.3.1 using Redsn0w:
Extract the RedSn0w zip archive we downloaded earlier.
Now launch redsn0w.
Now click on Browse and select the IPSW file corresponding to your iPhone or other iOS device that you are jailbreaking.
RedSn0w will now try to identify and process the firmware file. Once the firmware file has been identified click on Next.
RedSn0w will now start preparing jailbreak data based on the IPSW file.
After the jailbreak data has been prepared you will be led to the following screen.
By default the checkbox beside Install Cydia should be selected. You do not need to change any settings here. Click Next to proceed.
RedSn0w will now ask you to connect your iOS device to your computer and turn it off. You need to turn off your iPhone or iPod Touch after connecting it to the computer. Click on Next again.
The next screen will show you instructions to put the iOS device into DFU mode.
You need to hold and release the iPhone buttons in the said order to place it in DFU mode in order to proceed with the iPhone jailbreak. This is the last step for the user as after this RedSn0w will do everything automatically.
The iPhone will be jailbroken and then rebooted.
Click on Finish when you see Done! on your screen.
In a few minutes your iPhone will restart with the Cydia icon on the springboard.
Since, there was no custom IPSW involved as compared to the PwnageTool jailbreak, all your data on your iPhone should be intact eliminating the need to resync your data.
