PwnageTool 3.1.5 for creating iPhone 3.1.3 custom ipsw files is now LIVE! The infamous iPhone Dev-Team has updated their PwnageTool for Mac to make it compatible with the new iPhone 3.1.3 firmware.
This latest version of PwnageTool can jailbreak the original iPhone (Edge/2G), iPhone 3G, iPhone 3GS(older bootrom only with baseband 04.26.08) and iPod touch (1G and 2G non-MC model; 2G should also be pre-jailbroken) running on iPhone firmware 3.1.3. The custom .ipsw firmware files created with PwnageTool can update iPhone to firmware 3.1.3 without updating its baseband so that it can be unlocked to run on any carrier SIM. If you previously relied on blacksn0w unlock for iPhone 3GS, then this is NOT for you. iPod touch 3G is also currently not supported.
Note For Windows XP/Vista/7 Users: PwnageTool 3.1.5 is for Mac OS X only. Windows users should follow the guide posted here or here in order to jailbreak and unlock iPhone running with firmware 3.1.3.
The following step-by-step instructions will help you jailbreak your iPhone running on iPhone firmware 3.1.3 with PwnageTool 3.1.5:
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 4: Start PwnageTool 3.1.5 and select your device:
Step 5: PwnageTool 3.1.5 will now automatically detect the correct firmware for your device as shown in the screenshot below:
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 which will make your device almost impossible to unlock. 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 3.1.3 that you just cooked using PwnageTool 3.1.5 for your iPhone. 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.
This will make iTunes prompt you to select the location for your downloaded custom firmware 3.1.3. 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 3.1.3 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/iPod touch running on firmware 3.1.3.
