These are instructions on how to perform an untethered jailbreak of your iPhone 4 on 5.0.1 using RedSn0w for Mac. The Windows version of this tutorial here.

This procedure will cause you to upgrade your baseband potentially ruining your chances for an unlock. Please follow a tutorial on how to update to iOS 5.0.1 using a custom ipsw if you need an unlock.

If you want to jailbreak a lower firmware version you can find the appropriate tutorial here.

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. (Note: you do not need to download the 5.0.1 firmware if you are already on iOS 5.0.1)

Extract the RedSn0w zip file by double clicking it.


Step Two: (You can skip this step if iOS 5.0.1 is already installed on your device)
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 Jailbreak button


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 now 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.

Hi I'm getting ready to try this jailbreak on an iPhone 4 running 5.0.1. I just wanted to know if any of the problems have been fixed before I do so. I read all the previous comments and there seemed to be quite a few bugs. Have they been fixed and is it ok to try this jailbreak. I'm having issues with my old jailbreak. How do I remove that one so that I can jailbreak with this one. Thank you Tiffany

I have jailbroke my phone a week ago and yesterday begin noticing that my text messages wasn't popping up in the conversation as they did before, I had to close it out and then reopen. Now My phone won't access the Cydia app, my emails or allow me access to the web. If possible can someone please assist me with this

Hi, quick question about the tutorial link for the custom IPSW (for unlocking). That link says the jailbreak without BB upgrade would be tethered, but this tutorial here says the unlock will be untethered. I'm about to buy a 4 on ios 4.0 and bb 1.59 and i'm trying to figure out how much i should upgrade the software\firmware to. thanks!
