I have almost gave up and leave my currently updated 3.1.2 iPhone as jailed. But when doing final googling, I found this. Don’t know this will work on other device other than iPhone 3G, but logically it will.

Do check if you have qtcf.dll in your C: / Windows/System32/. If you don’t, you can get it from here. Follow the instruction in the page to copy and install it.

Then after that, do these steps:

1. Disconnect your iPhone from PC USB drive.
2. Run blackra1n.
3. Shoot “Make It Rain”
4. Connect the iPhone when it asked.

Note: If blackra1n hangs at “running” , open Task Mananger, end iTunes and iTunesHelper.exe processes.

• First thing first, if you are unlocking for T-Mobile USA, make sure to disable 3G.
• Run Cydia
• Select Manage > Sources > Edit > Add and type repo666.ultrasn0w.com in.  The “0″ in snow is actually a number, “zero”
• Wait for the sources to be refreshed
• Search “ultrasn0w” and install it
• Reboot
• Enjoy your freshly unlocked iPhone 3G

1. Open Cydia, tap on “Manage” at the bottom
2. Tap on “Sources”
3. Tap on “Edit” on top right then tap on “Add” on top left
4. Type in http://cydia.hackulo.us Cydia will warn you about copyright information just tap ok
5. Wait for repo to be added and updated.
6. From search or hackulo.us repo directory
7. Install Appsync for OS 3.0 do not install miPatch on os 3.0! If you do not download then sync cracked apps from PC/MAC/iTunes you may skip this step.
8. Install Installous
9. Restart your phone
10. Launch installous and have free fun.

Thats it, simple tap steps.

Appsync will allow you to sync the hacked apps through itunes, otherwise it will give out invalid application signature error.

For downloading from PC and syncing your apps with iTunes use www.appulo.us

Appulous is a free iTunes App Store in short created by people by sharing their applications from all over the world.

Troubleshooting

If you experience any problems during the installation or application installation steps, you may try this checklist.

1. Perform update on all cydia related packages. It will ask you to update first, do not skip it and update.
2. Do not forget to restart your phone
3. Install a free application from app store like “facebook” before installing applications from installous
4. First select download, wait for it to finish (100% complete) then tap “Downloads” section and install. If you do not see your app in that directory, then it is not complete yet. Double tapping on download may corrupt your downloaded file.
5. Make sure the file you are downloading works fine. Sometimes cracked apps may fail, so try another application or package to make sure everything works fine before searching for help.
6. If you encounter problems during application installation like package or executable not found etc make sure the following packages exists in your cydia, if not install them or re-install them to make sure everything is solid and packages are not corrupt. Installouse is dependent on these sub package libraries.
   1. Erica Utilities
   2. core utils
   3. grep
   4. Darwin CC Tools
   5. UUID Generator
   6. unzip
   7. gawk
   8. Curl (not sure if it was listed on packages but installous dependent)

If you still can not manage to solve your problem, drop a comment below including your problem. Me or someone else will try to help you for sure.

Solution A: (Windows 7 & Windows Vista users): Right click on redsn0w.exe and then click on “Properties”. Switch to “Compatibility” tab and make sure you check “Run this program in compatibility mode for: Windows XP (Service Pack 3)”. Now simply start the application by right clicking on the .exe file and then click on “Run as administrator”.

Solution B: If “Solution A” doesn’t work for you then make sure that you downloaded the correct firmware version file for your device.

• Firmware OS 3.0 (iPhone1,2_3.0_7A341_Restore.ipsw) for iPhone 3G
• Firmware OS 3.0 (iPhone1,1_3.0_7A341_Restore.ipsw) for iPhone 2G

Solution C: If “Solution B” doesn’t work then try this when you are stuck on “Waiting for reboot”: Press and hold both the “Power” and “Home” buttons for about 10 seconds then release only the “Power” button only while continue to hold the “Home” button for another 10 seconds. Your process should continue now.

Solution D: Make sure that you place all the required downloaded files in one single location (i.e. in same folder) as redsn0w:

• redsn0w.exe
• iPhone1,2_3.0_7A341_Restore.ipsw (iPhone 3G) OR iPhone1,1_3.0_7A341_Restore.ipsw (iPhone 2G)
• bl39.bin (for iPhone 2G only)
• bl46.bin (for iPhone 2G only)

Make sure you have kept all these files in one location under same folder.

Fix for Problem 2: If redsn0w.exe crashes during jailbreaking. Try the following solutions:

Solution A: Make sure that you places all the required downloaded files in one single location (i.e. in same folder) as redsn0w:

• redsn0w.exe
• iPhone1,2_3.0_7A341_Restore.ipsw (iPhone 3G) OR iPhone1,1_3.0_7A341_Restore.ipsw (iPhone 2G)
• bl39.bin (for iPhone 2G only)
• bl46.bin (for iPhone 2G only)

Make sure you have kept all these files in one location under same folder.

Solution B: redsn0w may crash for some users running Windows Vista & Windows 7. To get around freezing and crashing of redsn0w, right click on redsn0w.exe and then click on “Properties”. Switch to “Compatibility” tab and make sure you check “Run this program in compatibility mode for: Windows XP (Service Pack 3)”. Now simply start the application by right clicking on the .exe file and then click on “Run as administrator”. This should solve your problem on Windows 7.

Solution C: If both “Solution A” and “Solution B” didnt work for you then try this(Thanks to joey):  Choose not to install “Icy” when redsn0w gives you an option to install it. You can install “Icy” manually later when your are done with the jailbreak by following instruction under “Fix for Problem 5”.

Fix for Problem 3: If you are using a custom firmware 3.0 to update/restore using the guide here and getting 1604 error:

Solution A: You must make sure that you are updating from 2.2.1 in unlock and jailbroken condition.

Solution B: You must also make sure that you connect your iPhone directly to usb port on the backside of the computer. Avoid using usb ports in front and usb hubs.

Fix for Problem 4: You are stuck with firmware 3.0 and want to downgrade to 2.2.1: (Thanks to shoaib)

Most importantly you will have to set your iPhone into DFU mode NOT recovery mode, i tried recovery mode and got an error.

I’m sure most of you out there are just hitting shift + restore in iTunes and hoping it will work. But that method doesn’t set the phone into DFU mode.

1. Connect your iPhone and Press the home button for 5 seconds.
2. Press sleep/wake button for 10 seconds (do not release home).
3. Release sleep button but continue holding down the home button for an additional 30 seconds (your computer will start reinstalling drivers DO NOT RELEASE HOME BUTTON UNTIL 30 SECONDS ARE OVER)
4. iTunes will detect your phone in recovery mode (dont worry it will say “recovery” but is infact in DFU, you can make sure by checking the screen of your phone: Recovery mode= logo of USB connecting to iTunes and DFU mode = Blank screen
5. Press and hold left shift and click “restore”
6. Browse to folder containing the 2.2.1 firmware restore file. it should look like this iPhone1,1_2.2.1_5H11_Restore
7. Double click it and iTunes will start restoring.
   Once that is done iTunes will say INVALID SIM (if you are not using the legitimate SIM card).
8. Now you have a choice, you can either set the phone back into DFU mode (remember NOT recovery mode), or jailbreak using quickpwn 2.2.5 (old version).
9. I decided to jailbreak so that the “restore” option appears like how it is normally suppose to when you connect your iPhone. although setting the device back into DFU mode should also work.
10. Again press and hold shift and click on restore to browse to the custom “cooked” 3.0 firmware.
11. Voila! iTunes restores a fully functional 2G iPhone running on firmware 3.0

IMPORTANT REMINDER: Recovery mode can also be activated by holding the sleep and home button for 10 seconds, then releasing the sleep button while holding the home for additional 30 seconds… THIS IS WHAT U ***MUST NOT*** DO!!!!

Remember that throughout the process we are using DFU mode (I am emphasizing on this fact simply because recovery mode did not work for me).

PROBLEMS I(shoaib) FACED:

The shift + restore method was not functioning as it was suppose to. So if you face the same problem, tell me. i will show you how to bypass that.

Fix for Problem 5: You have successfully jailbroken your device but you cant find “Icy” (formerly Installer) on your iPhone:

Those of you who have jailbreaked your iPhone using redsn0w method above may have noticed no Icy(formerly Installer) on your iPhone. To install “Icy”, simply start “Cydia” on your jailbroken iPhone. It will prompt you to install upgrades, choose “Complete Upgrade” and then confirm the installation. Once this upgrade is done, restart “Cydia” and then follow the following steps:

1. Click on “Manage” and then click on “Sources”.
2. Click on “Edit” and then click on “Add”.
3. Enter “http://apt.ripdev.com” and then click on “Add Sources”. It will upgrade some files.
4. Now click on “Done” and then click on “Search” to search for “Icy”.
5. Find “Icy” (Only the word “Icy”) and install it.
6. You should now have “Icy” installer on your iPhone home screen.

Fix for Problem 6: You have successfully jailbroken your device but you are now unable to install jailbroken apps on iPhone OS 3.0:

Those of you who have updated to iPhone OS 3.0 (jailbroken) might have noticed that your jailbroken apps (Apps installed outside from App Store) have stopped working. Even if you have tried reinstalling them they wont work because these apps require a patched version of MobileInstallation file on your iPhone. To get around this issue, follow the guide here to patch the MobileInstallation file on your iPhone to get all the jailbroken apps working on your iPhone with OS 3.0.

Fix for Problem 7: You seem to have downloaded the correct iPhone OS firmware 3.0 .ipsw file but your Windows identifies it as a “.Zip” folder for extraction:

Some people have encountered this problem when downloading .ipsw file from Apple only to find it as an extraction(.zip) folder with a bunch files. To get around this issue:

1. Go to “My Computer” in Windows.
2. Press “Alt” button on the keyboard and then select “Tools” from the file menu and then click on “Folder options…”.
3. In “Folder Options”, switch to “View” tab and uncheck “Hide extensions for unknown file types” and then click ok.
4. Now simply go to the folder which contains that “.ipsw” file. You will notice that the extension for that file will now be reading as “.ipsw.zip”. Rename this file by removing the “.zip” extension from the end of the file so that the extension for the file becomes “.ipsw” only. Example: iPhone1,2_3.0_7A341_Restore.ipsw

Windows should now be able to read the file as valid “.ipsw” file for iTunes.

The reason is you need to upgrade Cydia’s Essential to the one compatible to the 3.0. Some user might getting a notification to upgrade Essential when opening up Cydia, while some are not.

If you are not the lucky guy who’s getting the notification, load Cydia, then go to Manage > Sources, then look for Telesphoreo in the list. If you see this line: “Distribution of Unix Software for iPhoneOS”, that means you have the *old* repository.

If you got the old version of Telesphoreo source, there is a quick fix for all that. Just go to Cydia , tap the Sources, Edit and add: apt.saurik.com/cydia-3.7

After that respring and go back to Cydia, you will then getting the notifications to upgrade all needed Essentials. Before updating these Essential, make sure to toggle off your autolock to avoid corrupted installation packages.

1. Connect your iPhone to iTunes
2. Download the firmware 3.0 from iTunes (I selected ‘Download Only’ instead)
3. After download completed, browse to C:/Username/App Data/Apple Computer/iPhone Software Update/
4. Download redsnow 0.72 from
5. Create a folder call Pawnage in the Desktop and place the 3.0 ipsw and redsnow 0.72 in it
6. Extract redsnow to the folder
7. Click Shift+restore if you jailbroken your iPhone before. Restore will wipe out all jailbreak data and clean up the iPhone before flashing the firmware. Navigate to the Pawnage folder created before and select the 3.0 ipsw file
8. Wait for around 7-10 minutes. You should have your iPhone updated to 3.0
9. After complete restoring, fire up redsnow.exe. Follow the steps mentioned, especially how to get to DFU mode.
10. Wait for around 30 seconds and your iPhone should be jailbroken

Stop at step 10 if you are not going to use custom firmware, or otherwise. Just connect the iPhone to iTunes again and click shift+restore, select the custom firmware to begin flashing the iPhone.
