Create a folder on your desktop and name it: Pwnage. Then download the following files and put into Pwnage folder:

How to Jailbreak iPhone 3G OS 3.0

Step 1
Double click PwnageTool dmg file to mount it


Click and drag the PwnageTool icon to Pwnage Folder you created and then open it from there.


Warning Box will Popup. Just hit the OK button.



Step 2

Make sure you select Expert Mode from Top menu



Step 3
Select your device i.e: iPhone 3G. A big Green check mark will appear on the selected device.
Now hit the big Blue Arrow button at bottom right to proceed.


Step 4
On the next page Pwnage Tool will automatically find the IPSW file. If not found then click “Browse for IPSW” button and select the downloaded IPSW file: iPhone1,2_3.0_7A341_Restore.ipsw. A check mark will appear next to it.


Then hit Blue Arrow Button to proceed.


Step 5
On the next page you will have 6 choices. Select the General and hit Blue Arrow Button to proceed.


Step 6
On the next Page you can decide your Root Partition Size where OS resides. Click activate the phone and Disable partition wipe-out.

***For the 3.0 firmware you may have to increase the size of your root partition slightly for the IPSW build to be successful. 695MB worked just fine for me***
***If the Enable Baseband check box is not greyed out, checkmark it. This allows the unlock to occur!***


The Bootneuter settings are greyed out for the iPhone 3G. Click the blue arrow button.


The next screen will show the Cydia settings menu. It allows you to create custom packages so you do not have to manually install them later.


Go to Download packages tab.and hit the Refresh button to display all the available packages. Double click your desired package, it will be downloaded and will be available under the Select Packages tab.


When you have downloaded your desired packages, go back to Select Packages tab and check mark the ones you want.

Step 7
Nowyou are  ready to build your custom firmware. Click the build button to select it, then click the blue arrow button to proceed.


Step 8
When both Bootloader files are found, you will be asked to Save your custom .ipsw file. Save it to the same Pwnage folder.


Step 9
PwnageTool will start building your custom firmware. Wait until it’s done.


If prompted enter your Administrator password and click the OK button.


When prompted if your iPhone has been Pwned before, Click No. It allows for a more thorough restore.


You will be asked to turn OFF the device. Make sure it is connected to the USB port.

  • You will be asked to hold the home button and the power button for 10 seconds.

If you failed to follow the instruction, it will show you a message asking if you want to retry?. Click Yes.
Unplug the iPhone from the USB. Turn it OFF, then turn it back ON. Reconnect it to USB and turn OFF the iPhone when prompted.


When followed correctly, Pwnage 2.0 will display a message telling your that it successfully entered DFU mode. iTunes will also pop-up.

May I jailbreak my iPhone 3G with OS3.0 using mac OS 10.4.11. I also bought my iPhone already unlocked. I can use any cellular network’s sim without any hassle.

@ Rich.. I suggest you first check whether PwnageTool runs on your OS or not. If it does.. then go ahead and perform the steps mentioned above to jailbreak your iPhone 3G

Rich July 9, 2009, 9:28 pm
