Jailbreak the iPhone 3G S and iPhone 4 on 5.0.1 firmware - NO UNLOCK

Posted: December 27, 2011

Who is this guide for?
  • iPhone 3G S, iPhone 4.
  • Must already be on 5.0.1 firmware.
  • I used OS X 10.7.2.

Thanks again go out to the iPhone Dev Team for providing this amazing, and FREE program for customizing the iPhone. You can visit their blog here. You can read their notes regarding this jailbreak here.

The iPhone I used (and the only iPhone I own) to make this tutorial is an iPhone 4 GSM. It was running 5.0.1 firmware and is an Apple unlocked phone purchased directly from them. Let's face it, no one has come up with a free unlock since the iPhone 4 debuted back in summer of 2010 (with modem firmware version 01.59.00) and I couldn't wait any more when one became officially available. Doing this makes jailbreaking so much more easier when you don't have to worry about preserving baseband to unlock your phone.

If you are already jailbroken using the tethered method, you can run this jailbreak right over your existing one to untether it. Just make sure to not reinstall Cydia.

One last thing before we jump in to the tutorial. Please read my disclaimer before proceeding. You've been advised. What you do to your iPhone is your responsibility and no one else's.

If you'd like to learn how this jailbreak was made possible, read pod2g's article here.





Step 1.

You will lose your unlock if you follow this tutorial. This is your only warning.

Download redsn0w 0.9.10b1 (or newer) here. Decompress the zip file and a folder will appear.

iPhone



Drag the redsn0w.app icon to your Applications folder. Overwrite any previous versions.

Step 2.

Note: My screen shots of redsn0w do not display a version number at the top. This is so I don't have to take the screen shots over and over again. Just make sure you are on the version listed above (or newer) and everything will be fine.

Launch redsn0w. Click Jailbreak. Redsn0w will hacktivate if it detects that the iPhone hasn't already been activated with iTunes.

iPhone



Make sure your iPhone is off and plugged in to your Mac. Click Next.

iPhone



Instructions for entering DFU mode will appear. They start right away and go very quickly so try to keep up!

Press and hold the on/off (sleep/wake) button for three seconds.

While holding the on/off (sleep/wake) button, press and hold the home button.

iPhone       iPhone



Release the on/off button, but keep holding the home button. I usually hold it until the screen turns white.

Redsn0w will display other messages in a pop up.

iPhone



Check Install Cydia, then click Next.

iPhone



A few more messages will appear in the program. Once you see Done, you can click the Cancel button to close the program while the process finishes on your iPhone

iPhone



You'll see a graphic that says jailbreak data is being downloaded on the iPhone. Text will scroll on the iPhone's screen.
