How to Perform an Untethered Jailbreak of Your iPhone 3GS (Mac) [5.0.1]



Instructions on how to perform an untethered jailbreak of your iPhone 3GS on the iOS 5.0.1 firmware using RedSn0w for Mac.

This procedure will cause you to upgrade your baseband potentially ruining your chances for an unlock.


Step One
Create a folder on your desktop called Pwnage

Download the latest RedSn0w from here and place it in the Pwnage folder. Likewise, download the 5.0.1 firmware from here and place it in the Pwnage folder.

Extract the RedSn0w zip file by double clicking it.


Step Two: (Skip this step if you're on iOS 5.0.1 already)
Connect your iPhone to the computer and launch iTunes.


Select your iPhone from the list of devices on the left. Now hold down Option and click the Restore button. Restore is preferred as it won't create any wasted space on your iPhone.


Navigate to the Pwnage folder on your desktop and select the 5.0.1 firmware ipsw. Click the Choose button to continue.


iTunes will now update your iPhone to the new firmware.

Step Three
Launch the redsn0w application from the redsn0w folder we extracted earlier.


Step Four
Once RedSn0w opens click the Extras button


Choose Select IPSW from the Extras menu.


Select the iOS 5.0.1 firmware ipsw from Pwnage folder on your desktop and click Open.


Click OK to dismiss the confirmation window.


When asked tell RedSn0w whether you have a new model or older model of the iPhone 3GS then click the theBack button.


Press the Jailbreak button to continue.


Step Five
Plug your iPhone into the computer and make sure its OFF then click the Next button


Step Six
RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here


Hold down both the Home button and the Power button for 10 seconds.


Release the Power button and continue holding the Home button until RedSn0w detects the device.


Step Seven
Your iPhone will now reboot


Step Eight
RedSn0w will prepare the jailbreak data.


Step Nine
Select Cydia from the list of options and click Next.


Step Ten
Your iPhone will now be rebooted again and RedSn0w will begin uploading the new RAM Disk and Kernel.


Step Eleven
Once this is complete you will be notified that RedSn0w is done. When your iPhone finishes rebooting (5 minutes or so) it will be jailbroken with Cydia on the SpringBoard.
