Jailbreak & Unlock (Mac) iPhone 4G,3GS,3G – iPod 4G,3G,2G – iPad
Step 1: iTunes
Make sure you are running the latest version of iTunes. If not, update iTunes then sync your device. Close iTunes when done.
Step 2: Download iOS Software
Create a new directory on your computer called “JailbreakUnlock”.
Download the 4.2.1 version software for your device. Important: Do not open the file, just save the file to the “JailbreakUnlock” folder that you just created. This file will take 5 to 15 minutes to download, as it is 600-700MB in size. WAIT! DO NOT GO TO STEP #2 UNTIL THE FILE IS DOWNLOADED
Step 3: Download Jailbreak Software
Download the Jailbreak software by clicking on the link below. Important: Do not open the file, just save the file to the “JailbreakUnlock” folder that you just created.
Step 4: Run Jailbreak Software
Locate the “JailbreakUnlock” folder that you created in Step #2. Verify that both downloads have finished. Once you have downloaded the PwnageTool, you are going to need to now run it. Once the PwnageTool is up and running, click okay to the pop-up window. Now if you have never used the PwnageTool you will notice there are many options presented to you. We will guide you through to process so do not get overwhelmed. The first thing you must do is click on the expert mode button in the top left hand corner of the screen (you will notice by default, Simple mode is selected, but we want Expert mode).
Step 5: Selecting Your Device
Now once you ensure Expert mode is selected, you will need to select the iDevice you are going to jailbreak, once you do select your iDevice a big check mark will appear over the one you selected. Click the Blue Arrow to continue.
Step 6: Browse
Now browse for the iOS 4.2.1 firmware you downloaded in step 2, click Open.
Step 7: Options
Select “General” and click on the blue arrow to continue. If your iPhone is NOT on an official carrier, select “Activate the phone”. If you are on an official carrier (ie. AT&T in the US), make sure this option is deselected (untick ‘Activate the phone’). If you want to use your iPhone on an unofficial carrier, tick this box (for iPod & iPad users, uncheck the checkbox). You can also increase the root partition at about 1,000 MB. Click the blue arrow to continue.
Step 8: More Settings
This part is optional. You are now in Cydia settings. From there, you can choose to pre-install jailbreak apps so that you don’t have to do it later. Dig around this option if you want to pre-install apps now. When done, click the blue arrow to continue.

Step 12: Building File
