Jailbreak Guide

Comex has pulled it off again with a great jailbreak. The jailbreak, “Jailbreakme.com 2″ is now released and all devices can once again be jail-broken. This one is very easy to use. You don’t even need a guide. Here are the steps:

1) Load safari on your iPhone
2) Type in http://jailbreakme.com
3) Slide to jailbreak
4) Wait and soon you have Cydia.

Just like spirit 1, this is a user-mode jailbreak which requires you to be able to load safari on the device. This means that you need to have an original card or one activation card like one you can buy from DITS here : DITS 3 in 1 Activation card.

Pls visit comex’s site and donate to him to help motivate him to find further jailbreaks in the future. He made a wonderful job and release it for free but you must keep in mind that he worked hard for the solution and he must pay for the server and the traffic that comes with the huge amount of user accessing it.

Those of you having problems where the device sits at the purple screen forever may benefit from clearing your cookies and restarting safari:

1) Put your device into Airplane mode.
2) Go to -> Setting -> safari -> Cookies -> Accept.
3) Double Tap home button.
4) Press and hold an icon to wiggle the task switcher icons and then quit Safari using the X.
5) Clear all Cache and cookies.
6) Open safari and go to jailbreakme.com and try again.

Unlock Guide

The iPhone Dev Team has released an update to Ultrasn0w that unlocks the iPhone 4. If you decide you need to unlock your baseband in order to use your iPhone with unsupported carrier, make sure you don’t update your firmware to any future Apple updates (such as 4.1 when its released) since that will terminate the unlock. You can install Ultrasn0w from Cydia (you need to jailbreak in order to have Cydia). Ultrasn0w is in the dev-team repository, which is a default repository in Cydia. Just search Cydia for ultrasn0w, install the package and restart your device. You can now enjoy your device on any supported or unsupported carrier.

If you are reading this guide, it means that you, as me, as well as many others got stuck at some point. iPhone OS 4 is nice and it really have some new and very useful features, but than again, what features are good for if the device is impossible to use? Until Apple will release a reliable firmware 4.xx for iPhone 3G you can downgrade the firmware to one that enables you to sent messages, make phone calls, read mail, write notes.. you know , the things for what you bought your iPhone in the first place.

So what will this guide explain?

- Slow iPhone 3G iOs 4 solution
- Downgrade iPhone 3G from firmware 4 to 3.1.3
- Restore error in iTunes code : 1601, 1602, 1603, 1604, 1608, 1609, 1611, 1612.
- Restore error in iTunes code : 1002, 1011, 1013, 1014, 1015.
- In-out Restore Mode using RecBoot
- Redsn0w is unable to recognize the 3.1.2 or 3.1.3 firmware.
- Cydia error : apt.saurik.com host unreachable.
- Saurik repository : dev-team repository to Cydia (repo666.ultrasn0w.com).
- Accessing iPhone as root solution

First of all, and very important : Save (write down) all your important data like:　contacts, notes, mail, SMS. It is impossible to restore the iOs4 backup to the 3.1.3 firmware. Be warned of the risk of losing your data and act accordingly. Yes, you can restore back iOs4 or 3.1.3 Back and Forth…and Back Again as many times you need, but than again, that will make you loose time.

The problems began for me with this first step. Here are the correct information regarding the downgrade:

Download the required old ipsw firmware files. (Download links: iOS 4, 3.1.3, 3.1.2)
Put your device into DFU mode (not recovery mode).

* Connect your iPhone to your computer.
* Turn iPhone off.
* Start iTunes.
* Hold Power and Home buttons together for 10 seconds or so.
* Release Power button but keep holding the Home button until your computer recognizes a new USB device.
* iTunes will now recognize your iPhone.

Note: Your iPhone screen at this time should be blank (black in color), if not, then you are most likely in Recovery Mode, not DFU mode.

The solution is correct but you might find yourself in the situation where you cannot restore the phone and iTunes will display one of the errors: 1601, 1602, 1603, 1604, 1608, 1609, 1611, 1612. If you got one of this errors the only way is for you to downgrade iTunes to a version that allow you to restore since the last version ( 9.2.14) will make the same error again and again. I had an old version of iTunes 9.0.3 (you can download from Apple ) already installed on another computer and so was able to restore my phone to the 3.1.3 firmware. At the end of restore process iTunes will give one of the following errors : 1002, 1011, 1013, 1014, 1015. Do not worry , at this step the restore process is complete; Just use RedBoot to kick iPhone out of Restore mode (all about RecBot including links and source code can be found here: iPhone-iPod-iPad-recovery-mod-tool-RecBoot ). If something is wrong pls go to the beginning of the guide and start all over.

Now you will need to exit your device from Recovery Mode. To do this, download a program called RecBoot (Windows / Mac). Run it and the click on “Exit Recovery Mode” button. Your device will now restart normally.

This is it, you should now be able to jailbreak your device on this older OS. For iPhone 3.1.2 firmware, you can use blackra1n, PwnageTool, redsn0w, sn0wbreeze, ultrasn0w and blacksn0w to jailbreak and unlock your iPhone and iPod touch. For iPhone 3.1.3 firmware for iPhone 2G, 3G, 3GS and iPod touch 1G/2G, you can use redsn0w 0.9.3, redsn0w 0.9.4, sn0wbreeze, PwnageTool 3.1.5. Unlocking can be done using ultrasn0w or blacksn0w. iPhone 3.1.3 (on devices with new bootrom and baseband) can use Spirit to jailbreak iPhone 3GS/3G and iPod touch 3G/2G.

Wow… we made it… For a big bunch of you Yes, the journey stops here. As for me and other unfortunate people, the journey just begins . But don’t worry, we’ve figured it all out, and we’ll give you instructions for other problems too.

So here we are, we found another problem : Redsn0w is unable to recognize the 3.1.2 or 3.1.3 firmware. Strange since before (3 mount before) it worked… Something happened in the mid-time but cannot figure out what. I tried with redsn0w 0.9.3, redsn0w 0.9.4 on firmware 3.1.2 and 3.1.3 using Windows Xp, Windows Vista and Windows 7 and with different versions of iTunes installed : 9.2.1.4 and 9.0.3.
So I decided to use Spirit to jailbreak my phone. Follow this tutorial on how to use Spirit to jailbreak iPhone3G.

Here comes another problem and this problem occurs especially for the guys who are in China at the moment of this process (like I am now ) : The Cydia version that gets installed by Spirit is an old version and have some errors making it impossible for you to install anything. While trying to upgrade the essential packages I constantly receive this error : apt.saurik.com host unreachable. I tried to unlock my phone using ultrasn0w by manual adding the dev-team repository to Cydia (repo666.ultrasn0w.com to Cydia. That last “o” is actually the number zero “0”. If you use the letter “o” you’ll get an error). Problem is that there are some dependencies that should be download from saurik’s repo… and here we are again.. impossible to unlock or use my iPhone3G.

I found the solution on the modmyi forum and I will explain how to do it.

the final host file should be like this

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
echo ”
93.184.221.133 cache.saurik.com
”

So in order to make this mod you need to access the file located at /etc/host . And in order to do this you need to be able to root-access your device. So there is a new problem and of course we’ve got an answer to it. The package that gives you root access to your iPhone is named afc2add and can be found in saurik repo ( that you can’t access for the present moment) but also on ModMyI.com repo that is available. It does come with one dependency but that will pose no problem ( at least for me it didn’t). Just follow the picture I attached and go in Cydia and enter : Manage than Sources and than navigate trough ModMyI.com repo until you find afc2add package. Install the package.

Now you are able to access your iPhone at a root level, and you can do this using iPhone Explorer or with Total Comander after installing T-Pot plugin. I use Total Commander on regular bases and for this task too.

This was the final step for me and for all the unfortunate Asian friends that struggle with the same problem. Modifying the host file will allow Cydia to update all its sources, upgrade to the latest version and so unlock your iPhone 3.1.3
I have once again an functional and quick iPhone3G.

I hope you enjoyed this journey and I hope this guide was useful for you. If you find this guide useful, please leave a comment.

The iPhone Dev-Team (Comex) has released JailbreakMe 2.0 (aka Star) which can jailbreak all iOS devices on their latest respective firmware like iOS 4.0 / 4.0.1. This does not work with iOS 4.1 Beta release. Since JailbreakMe 2.0 is a userland jailbreak, what this means is that you run it right in your iOS Safari browser to jailbreak the device. It can’t get simpler than that !

One thing which is important to note here is that this jailbreak tool doesn’t hacktivate your device. You will need an original supported SIM card to activate your phone with iTunes. If you don’t have an original SIM, you can follow the instructions in this video guide posted here to activate your phone without having the original SIM card.

Step 1: Start iTunes and backup everything from Contacts, Calendars, Photos, Videos and Apps.
Step 2: Update your iPhone 4, 3GS or iPhone 3G on the latest iOS 4.0.1 firmware with iTunes. Download links for the firmware and iTunes 9.2.1 can be found below.
Step 3: Once you are done with the update, make sure you are connected to a WiFi network. I haven’t tested it on 3G so I recommend using it on a reliable WiFi network.
Step 4: Open Safari on your iPhone 4, 3GS or 3G and navigate to http://jailbreakme.com.
Step 5: “Slide to Jailbreak” to begin the jailbreak process.
Step 6: Wait till the jailbreak tool download the required files..
Step 7: Once the download is completed, it will automatically start the jailbreak process. Just don’t do anything silly at this point. Wait till the jailbreak process is completed.
Step 8: Once done, you will be greeted with the following message.
Step 9: Close the browser and look for Cydia. You should now have it on your phone!

As you may have already seen, RecBoot is a utility which allows the user, you, to kick the connected device(s) into and out of recovery mode.

Recovery Mode

“This handy little utility plays an important role in finishing off the downgrade.”
- LifeHacker

“In a few seconds, RecBoot would help you out of plug-me-into-iTunes recovery mode and you’ll boot right into your freshly downgraded 3.1.3.”
- FindTut

“The tool is dead simple, and everybody can use it. It has two buttons ‘Enter Recovery Mode’ and ‘Exit Recovery Mode’ , and you don’t have to be a genius to know which one to click.”
- FunkySpaceMonkey

The newest version of RecBoot for OS X can be found here: RecBoot Intel (82957)

Updated.
The above version of RecBoot is 1.0.2. It is a little bit different to past versions and I would appreciate it if you read the README.txt before commenting.

Windows Users
The long awaited update is here: RecBoot no longer requires libusb! The next update to RecBoot would make it interact with MobileDevice.h, and I’ve been chatting with iH8sn0w on IRC on getting this done.

So, here’s the deal: I’ve been getting TONS of emails from people saying that RecBoot wasn’t working for them because of libusb. This update makes RecBoot use iTunnel instead of iRecovery, which is based around MobileDevice.h, which means no libusb!

If you wish to enter Recovery Mode, however, you will need to place iTunesMobileDevice.dll in the RecBoot folder. I cannot provide this due to legal reasons. I could have made RecBoot point to the DLL from the registry, but I’m not going to, it’s just a quick open source thing I created for the community that isn’t a big deal, feel free to do whatever you want with it, use the batch files and everything else in the folder. The source code can be downloaded here. RecBoot is in your hands now.

You can Download RecBoot 1.1 here

Linux Users
No, we didn’t forget you either! Thanks to the magic of @malontop we can now offer you a version of RecBoot for Linux! If you have any questions, feel free to contact him via Twitter. You can download the Linux version from here: RecBoot for Linux (1129)

10.4.x and PowerPC Users
If you’re having difficulties with RecBoot on a 10.4.x Mac and/or a PowerPC Mac, it won’t be fixed. It just won’t be supported at all. So, a detailed “How-To” is available here for you. Hopefully this stops ALL emails wanting a 10.4.x and PowerPC version.

Sn0wbreeze 1.8 has been released. This is by the same developer who is behind other popular iPhone jailbreak tools such as sn0wbreeze 1.6 and 1.7 for iOS 4, sn0wbreeze for iPhone 3.1.3, f0recast and BlackBreeze. Just like the PwnageTool for Mac, Sn0wbreeze 1.8 can jailbreak iPhone 3GS (old bootrom, and already pwned on iOS 4.x), iPod touch 2G (non MC model) and iPod touch 3G on iOS 4.1 Beta. iPhone 3G users will have to jailbreak using Redsn0w.
So if you have a Windows machine, you can use Sn0wbreeze 1.8 to create custom firmware files without the upgraded baseband. Again, only the following devices are supported.

* iPhone 3GS (old bootrom and already jailbroken on iOS 4.x)
* iPod touch 2G (non MC model)
* iPod touch 3G

Warning: If you rely on an unlock, DO NOT update to iOS 4.1.

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 iOS 4.1 firmware file for your version of iPhone or iPod touch. 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 iOS 4.1 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 4.1 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 custom firmware 4.1. 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 iOS 4.1 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 4.1.
Step 10: Once you are done with the jailbreak process. You can now restore all your settings, apps, music, contacts and photos to the newly installed iOS 4.1 by restoring the backup that you made in Step 2 from iTunes.

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.

PwnageTool 3.1.5 Jailbreak
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.

This will make iTunes prompt you to select the location for your downloaded custom firmware 4.0. 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 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.

The all-in-one untethered iDevice jailbreak for iPhone 3.1.3, iPad 3.2 and iPod touch 2G/3G is finally here. Available for both Windows and Mac OS X, Spirit is a userland jailbreak but it does not work out-of-the browser as previously thought. It is in fact a simple one click app, like Blackra1n which can jailbreak (not unlock) any Apple iDevice on iPhone 3.1.2 or 3.1.3.

Spirit on Windows for iPhone and iPad
It is also important to note here that Spirit wont unlock your phone. It is a jailbreaking tool only that will only work on devices which are activated via iTunes. So if you rely on an unlock, DO NOT upgrade to stock firmware or you’ll be stuck. Unlock for iPhone 3.1.3 on 05.12.01 baseband wont be out before the next iPhone hit the shelves. And that wont be before June/July of this year.

Make sure that you have your SHSH files saved. You can jailbreak without saving SHSH files but you wont be safe once Apple patches the exploit used by Spirit. Follow the instructions posted here to save your SHSH blobs.

What’s Spirit?
* Spirit is an untethered jailbreak for iPad, iPhone, and iPod touch on the latest firmwares.
* Spirit is not a carrier unlock.
* If you currently are using a tethered jailbreak, you have to restore to use Spirit. Do not upgradeif you use an unlock on an iPhone 3G or 3GS. (You can, however, restore to 3.1.2 if you have SHSH blobs for that version.)

Requirements
* Any iPad, iPhone, or iPod touch on firmware 3.1.2, 3.1.3, or 3.2.
* An activated device: one not stuck on the Connect to iTunes or Emergency Call screen.
* Any version of iTunes 9 (including 9.1.1).

Note: On iPad, all this is still sort of beta. Some packages in Cydia, not designed for iPad, might screw up your system and require you to restore. Be careful. (And no, Cydia’s appearance is not final.)

iTunes 9.1 causes syncing issues for many users (specially on Windows), who were jailbroken on iPhone 3.1.2 (tethered) using blackra1n.
But now thanks to ih8sn0w, this issue can now be fixed by using BlackBreeze.
To fix blackra1n RC3, simply start BlackBreeze and select blackra1n RC3. Now select the directory where you want to save the fixed blackra1n RC3 executable file. You’ll now notice that a new file by the name of blackra1n-fixed.exe would have been created in the directory where you chose to save it.
Now start this fixed version of blackra1n RC3 and use this to start your device (tethered). Once done, you’ll now be able to sync your iPhone (firmware 3.1.2) safely with iTunes 9.1.

The final version of Blacksn0w RC2 is now available on Cydia.
This version brings fix for WiFi loss, and boot loops issue which was hampering users in the last ‘test’ release.
The installation instructions for blacksn0w RC2 (Final) are exactly similar to the last release.

F0recast enables iPhone 3GS, 3G, 2G and iPod touch 1G/2G/3G users to know all they ever needed to know about unlocking and jailbreaking their iPhone and iPod touch.

F0recast will help report you your iPhone or iPod touch serial number, the baseband version you running, bootloader version info, model number (whether it is MC or not), unlocking info with appropriate tool for unlocking like blacksn0w and ultrasn0w and last but not the least, whether your jailbreak will be tethered or not.
To use F0recast on a Mac, simply connect your iPhone or iPod touch with your iMac or MacBook when iTunes is running and then run this app. It will report all the necessary info off your iPhone/iPod touch.

iPhone Dev-Team has confirmed that Gull1hack and Blacksn0w V2 by the Gull1hack team is fake. Gull1hack was supposed to jailbreak all iPhone and iPod touch devices on the new bootrom untethered.
Stay away from all such tools as they could harm your phone or computer by running trojans and viruses.

George Hotz has confirmed via his twitter account that he has a working exploit which can unlock the latest 05.12.01 baseband which Apple bundled when they released iPhone 3.1.3 for iPhone and iPod touch earlier this month.

Last week, another iPhone hacker and developer named Sherif Hashim also found an exploit for the latest baseband. This exploit was sent to iPhone Dev-Team and they confirmed that it was working but didn’t give any ETA on when or if they are going to release a tool which is going to unlock iPhone 3.1.3 05.12.01 Baseband for iPhone 3G and 3GS. Maybe they don’t want to waste this all important exploit for this minor update and instead will use it when the major update such as iPhone 3.2 or iPhone 4.0 is released with the next-gen iPhone 4G.

Sn0wbreeze 3.1.3 V1.5.1 has been released. This minor update brings Youtube fix which was hampering users in the last release. Also added in this version is more speed and reliability. Unfortunately, Blacksn0w unlock for iPhone 3GS is still crippled in this version. If you have iPhone 2G, 3G or iPhone touch 1G/2G, you can use sn0wbreeze to jailbreak iPhone OS 3.1.3.

Instructions for jailbreaking using sn0wbreeze V1.5 are exactly similar to the last release. 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 using ultrasn0w.

PwnageTool 3.1.5 for creating iPhone 3.1.3 custom ipsw files has been released.
The 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: PwnageTool 3.1.5 is for Mac OS X only.

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 5: PwnageTool 3.1.5 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 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.

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.
