The official release of PwnageTool 4.0 for creating custom ipsw files for iOS 4.0 is now released! The infamous iPhone Dev-Team has updated their PwnageTool for Mac to make it compatible with the newly released iOS 4 for iPhone 3GS, iPhone 3G and iPod touch 2G (non-MC model only). The custom .ipsw firmware files created with PwnageTool can update iPhone to iOS 4 without updating its baseband. iPod touch 2G MC model and iPod touch 3G is currently not supported.
Some important notes from Dev-Team’s blog. MUST READ:
iPhone 3GS
Summary: Currently, PwnageTool only works on previously jailbroken 3GS devices with the old bootrom.
* If you have a Jailbroken iPhone 3GS with the OLD BOOTROM and you DID NOT use Spirit to jailbreak then you can create the ipsw with PwnageTool 4.0 and restore with your jailbroken recovery mode.
* If you have an iPhone 3GS with the NEW BOOTROM this is NOT supported by PwnageTool 4.0

iPhone 3G
* If you have a Jailbroken iPhone 3G at 3.1.2 (but not jailbroken with Spirit) then you should create the ipsw with PwnageTool 4.0 and restore from recovery mode or DFU mode.
* If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.0 ipsw using DFU mode.
* If you have a Jailbroken 3.1.3 iPhone 3G it is very possible that this can fail from recovery mode, if this failure happens you will need to restore using DFU mode.
* As an alternative to PwnageTool, you can use redsn0w on iPhone 3G (on both Windows and Mac) as mentioned in our last post.

IMPORTANT! Whenever you need to enter DFU mode, you will need to do so using PwnageTool.

iPod touch 2G
* If you have an iPod touch 2G (non-MC model) that is jailbroken (but not with Spirit) then you can restore using recovery mode.
* As an alternative to PwnageTool, you can use redsn0w on non-MC iPod Touch 2G (on both Windows and Mac) as mentioned in our last post.

The following step-by-step instructions will help you jailbreak your iPhone running on iOS 4 with PwnageTool 4.0.
Step 1: Download and install the latest version of iTunes.
Step 2: Now start iTunes and sync your iPhone with your PC so that it backs-up all your important data including settings, apps, music, contacts and photos.
Step 3: Download PwnageTool 4.0 and the original iOS 4.0 for your version of iPhone or iPod touch. Move all these files to your desktop.
Step 4: Start PwnageTool 4.0 and select your device.
Step 5: PwnageTool 4.0 will now automatically detect the correct firmware for your device.
Step 6: Click on “No” when PwnageTool asks you “Do you have an iPhone contract that would activate normally through iTunes?
Clicking on Yes will update your baseband to the latest version. Click on Yes only if you are on an officially supported carrier like AT&T.
Step 7: PwnageTool will now create the custom .ipsw file for your iPhone which will be jailbroken.
The following “ihaz Success” screen will confirm that the requested .ipsw file has been created successfully.

Step 8: Once the .ipsw file has been created, you will now have to restore your iPhone to this custom firmware 4.0 that you just cooked using PwnageTool 4.0 for your iPhone or iPod touch. Click on your phone icon from the sidebar in iTunes. Now press and hold left “alt” button (“Shift” button on Windows) on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release the “Shift” button.

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 4.0 on your iPhone. Your iPhone screen at this point will be showing a progress bar indicating installation progress. After the installation is done, iPhone will restart automatically and you should now have a fully jailbroken iPhone running on iOS 4.

Step 10: Once you are done with the unlocking and jailbreak process. You can now restore all your settings, apps, music, contacts and photos to the newly installed firmware version 4.0 by restoring the backup that you made in Step 2 from iTunes.

Sn0wbreeze 3.1.3 V1.5 has been released which adds support for iPod touch 2G (older non-MC model).
Follow the complete step by step guide posted here to jailbreak your iPhone and iPod touch using sn0wbreeze 3.1.3 V1.5. Once you are done with jailbreak, you can then unlock your iPhone 3G and 3GS using ultrasn0w or blacksn0w.

I would strongly suggest iPhone 3GS users to stay away from this release as this release like all previous versions sends iPhone 3GS into an infinite loop after first reboot. If you have a Mac, I will strongly suggest you to use Dev-Team’s PwnageTool 3.1.5 which can jailbreak iPhone 2G, 3G, 3GS (older bootrom and with baseband 04.26.08).

Sn0wbreeze 3.1.3 has been released which can jailbreak iPhone 2G, 3G and iPhone 3GS on the latest iPhone 3.1.3 firmware.
It will work with iPhone 3GS only if it has the older bootrom (non-MC model). iPhone 3GS users who have upgraded to the stock 3.1.3 are still out of luck.
Follow the simple step by step guide below to jailbreak your iPhone 2G, 3G and iPhone 3GS (old bootrom only) on iPhone firmware 3.1.3 using Sn0wbreeze.
This version of Sn0wbreeze is for iPhones only. iPod touch 1G/2G (older non-MC models) can use redsn0w to jailbreak on 3.1.3 firmware. iPod touch 3G is currently not supported.

Step 1: Download and install the latest version of iTunes.

Step 2: Now start iTunes and sync your iPhone with your PC so that it backs-up all your important data including settings, apps, music, contacts and photos.

Step 3: Download Sn0wbreeze and the original iPhone OS 3.1.3 for your version of iPhone (download links given below). Move all these files to your desktop.

Step 4: Start Sn0wbreeze and select “Simple Mode”.

Step 5: Sn0wbreeze will now ask you to browse for your .ipsw file. Select the correct 3.1.3 firmware .ipsw file by clicking the “Browse” button. Sn0wbreeze will verify the selected file.

Step 6: Click on “Yes” when Sn0wbreeze asks you “Do you want to activate your iPhone?” for hacktivation. Click on “No” only if you are on an officially supported carrier like AT&T.

Step 7: Sn0wbreeze will now create the custom .ipsw file for your iPhone which will be jailbroken.

Step 8: Now you will have to restore your iPhone to this custom firmware 3.1.3 that you just cooked using Sn0wbreeze for your iPhone. Click on your phone from the sidebar in iTunes and then press and hold left “Shift” button on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release the “Shift” button.

This will make iTunes prompt you to select the location for your downloaded custom firmware 3.1.2. Select that custom .ipsw file 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 3.1.2 on your iPhone. Your iPhone screen at this point will be showing a progress bar indicating installation progress. After the installation is done, iPhone will restart automatically and you should now have a fully jailbroken iPhone running on firmware 3.1.2.

Step 10: Once you are done with the unlocking and jailbreak process. You can now restore all your settings, apps, music, contacts and photos to the newly installed firmware version 3.1.3 by restoring the backup that you made in Step 2 from iTunes.

Note for iPhone 3G and 3GS Users (New Bootroms): We strongly suggest that you stay away from this official upgrade until and unless the DevTeam or George Hotz releases new jailbreaking and unlocking tools for 3.1.3 firmware. We will let you know when it will happen. In the meantime you can follow our complete jailbreaking and unlocking guide for iPhone 3.1.2 firmware using blackra1n, PwnageTool, redsn0w, sn0wbreeze, ultrasn0w and blacksn0w.
