This guide is for PCs running Windows and only for the iPhone 3g and 3gs. (Not for iPhone 4)

The iphone 3g/3gs 4.2.1 unlock became available to the public two weeks ago (all basebands). This guide will show you how to unlock your iPhone running 4.2.1. In order to succeed with this process you will need to follow the steps below one by one without skipping any of them. (You may think you know what your doing but the truth is that if you knew, then you wouldn't be here reading this guide). So, with all that said lets get right to it. First, make sure you have connected the iPhone (3g or 3gs) to the computer and then start with step one below.

This works on all basebands including 05.14.02 and 05.15.00 up to 4.2.1. Make sure to use firefox to download and save the ipsw file.

Step 1.
Download the 4.2.1 ipsw from here: http://iclarified.com/jailbreak/iphone3g/firmware.php (with firefox only) and save it to a location on you C drive that you will remember later.

Step 2.
Download redsn0w 0.9.6b1 from here: http://rapidshare.com/#!download|500l32|433785855|redsn0w_win_0.9.6b5.zip|11179 and install.

Step 3.
Run redsn0w, click the "Browse" button and go to the path where you saved the 4.2.1 file earlier and select it.

Step 4.
redsn0w will process the file and if all good it will continue, otherwise it will say "ipsw not recognized" and that is only if you dowloaded it with a different web browser than the one specified above (firefox). If all good, continue.

Step 5.
On this step make sure you mark the field where it says "install iPad baseband". What this does is that it will update the current baseband on your iPhone to an iPads baseband. This is necessarry to unlock your iPhone 3g and 3gs. Continue.

Step 6.
redsn0w will install the 4.2.1 on your iPhone, then respring. After it did so, open Cydia.

Step 7.
Go to "Manage", "Edit", then "Add" (top left) and enter this source http://repo666.ultrasn0w.com This will get ultrasn0w 1.2 to unlock your iPhone.

Step 8.
Install and run ultrasn0w 1.2, then respring.

Step 9.
Your iPhone should now be unlocked and work on any GSM network.

Step 10.
Enjoy !

iPhone developer and hacker Nadeem97 has released PwnageTool bundles which can jailbreak iPhone 4 and 3GS untethered on iOS 4.2.1, in the process preserves the old 01.59.00 baseband for iPhone 4 and 05.13.04 baseband for iPhone 3GS so that you can unlock with the existing version of Ultrasn0w.

Step 1: Download untethered PwnageTool bundle for iPhone 4 and iPhone 3GS from here. Extract the .zip folder, in there you will find two .bundle files, info.plist and some other files.

Step 2: Download PwnageTool 4.1.3 and copy it to your desktop. Right click, and then click on “Show Package Contents” as shown in the screenshot below.

Step 3: Navigate to Contents/Resources/FirmwareBundles/ and paste iPhone3,1_4.2.1_8C148.bundle for iPhone 4, or iPhone2,1_4.2.1_8C148a.bundle for iPhone 3GS in this location.

Step 4: Now navigate to Contents/Resources/CustomPackages/CydiaInstaller.bundle/ and here copy the info.plist file and then simply close this folder.

Step 5: Download iOS 4.2.1 for iPhone 4 or 3GS. Move this IPSW file to your desktop.

Step 6: Start PwnageTool in “Expert mode” and select your device:

Step 7: Browse for iOS 4.2.1 firmware for your device.

Step 8: Now before proceeding with the create-the-bundle process, make sure “Activate the Phone” option is unchecked under “General”, and “Cydia Installer” package is selected under “Cydia Packages” option. Once done, select “Build” to start creating custom 4.2.1 firmware file:

Step 9: PwnageTool will now create the custom .ipsw file for your iPhone which will be jailbroken.

Step 10: Now follow the following steps to enter DFU mode:

• 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

Step 11: Start iTunes, click on your iOS device icon from the sidebar in iTunes. Now press and hold left “alt” (option) button on Mac, or Left “Shift” button if you are on Windows on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release this button.

This will make iTunes prompt you to select the location for your custom firmware 4.2.1 file. Select the required custom .ipsw file and click on “Open”.

Step 12: 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 firmware 4.2.1 on your iPhone. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your iPhone will restart automatically and you should now have a fully jailbroken iPhone 4 or 3GS, untethered on iOS 4.2.1.

Step 13: Once you have jailbroken your iPhone 4 or 3GS, you can safely unlock it on iOS 4.2.1 (on 01.59.00 baseband for iPhone 4 and 05.13.04 baseband for iPhone 3GS) using Ultrasn0w 1.2.

UPDATE 1: The link above of PwnageTool bundle for iPhone 4 and 3GS has been updated. All problems related to Cydia should now be fixed. Thanks to Nadeem97 for the heads up!
