How To Jailbreak iOS 5 On Your iPhone 4, 3GS, iPad or iPod touch Using Redsn0w [Jailbreak Superguide]



The Redsn0w software by DevTeam has always allowed you to jailbreak your iOS device, giving you complete control over your iPhone, iPad or iPod Touch (see why you should jailbreak here). This morning, though, redsn0w version 0.9.9b5 was released with iOS 5 support, meaning you can now jailbreak devices and run Cydia apps on devices with iOS 5 installed. Here’s how to jailbreak iOS 5!

Warning: This is a tethered jailbreak, meaning that every time you reboot the device, you’ll need to use redsn0w again or else lose all your jailbreak data. Also, redsn0w will not carrier unlock your device. This should work on any device capable of running iOS 5 short of the iPad 2 or the iPhone 4S, which still hasn’t been jailbroken, but we’ve only tested it on the iPhone 4 and the iPad. Be careful!


  • A compatible iOS device
  • That same device updated to firmware iOS 5
  • iTunes 10.5
  • redsn0w 0.9.9b5 for Mac.

Please backup all your information using iTunes before following this tutorial.

1. Download redsn0w and extract the ZIP. Double-click to open redsn0w application.

2. Click the ‘Jaibreak’ button below the text. Now it will ask you to connect the device to your Mac/PC and then turn it off, do so and click ‘Next’. Now follow the on-screen instructions to proceed.

3.  The device will reboot while redns0w prepares the jailbreak data.

4. Then choose if you want to install Cydia and click the ‘Next’ button.

6. The device will reboot showing ‘Downloading Jailbreak Data’ logo and then some code on the device’s screen, while redsn0w sends modified files to the device. You will be notified once redsn0w is done. Let the rest of process continue on the device, please be patient.

7. After it reboots, your device should now be jailbroken with Cydia on the homescreen.

8. For booting up tethered, open redsn0w and click the “Extras” button below the jailbreak button.

9. Select “Just Boot” from the “Extras” menu.

That’s it! You’re done! Let us know how you got along in the comments.

    Why does that look more like a Galaxy S II than an iPhone?

  • Geek for e

    In the last month I can honestly say I have rebooted my phone once. Why on earth would you do this more than that?

  • Nokomera1

    thats because its an ipod

  • GGGloster

    If I do this, do I need to change somekind of password?
    Your 2 year old article suggests so…

  • Idol782002

    Is there a version for PC?

  • djrobsd

    Seriously?  Is your phone jail broken?  Most people with jail broken phones running apps like BiteSMS have to reboot once or twice a week.

  • djrobsd

    Looks promising, I’ll wait until an untethered one comes out.  Looking forward to getting my lock screen calendar, bitesms, airplay hack, and activator apps back. :)  Why did Apple spend so much effort developing the new notification center and neglected to think that MAYBE we might want to respond to text messages without having to switch out of the app we’re in or have to enter our unlock code? ;)

    Any reason why Cydia does not start up? Run Cydia and it just flashes and goes back to the icon screen.

    Really?  Mine’s jailbroken primarily for SBSettings and Infinifolders, and I rarely ever have to reboot.

  • Lucid129

    It seems like you didn’t take the hint that it’s a tethered jailbreak.

  • Keith

    Phone still connected. The Cydia icon is a grey block.

  • Fligabob

    Boot it tethered. That should get it working.

  • Dan

    i have same problem

  • Dan

    tethered doesnt mean it must be plugged in just that if you reboot u have to plug in to reboot it

  • Kyle Bashour

    you have to “rejailbreak” not plug it in. Basically do the jailbreak again, but DO NOT check install cydia – uncheck that, and check “just boot tethered”

    Anyone know if Siri works on Jailbroken iPhone4?

  • beewhy

    well if your out and it dies idiot

  • KJ

    I jailbroke fine, and installed bitesms…but when it reboot, I can’t seem to get it back in DFU mode.  And it hangs on the apple logo.  Did I just un-jailbreak it?  And now have to re-jailbreak and then be super-careful about rebooting?  I’m getting confused, I guess this tethered thing isn’t for me.  I’ve jailbroken numerous times, but they’ve all been unthered.  

    Geez..I think I just bricked my won’t do anything.  Yay.
