iOS 4 was released today for iPhone and iPod Touch for free. While most people have upgraded easily, some of us have been waiting for a jailbreak. Here’s a simple guide on how to jailbreak your iPod Touch and get features like multitasking and home screen backgrounds that Apple has weirdly disabled for 2G. Make sure you follow the guide correctly and make a backup using iTunes.
Jailbreak iOS 4
- Download iOS 4 for your iPod Touch
- Download redsn0w 0.9.5b5-4 [links at the end]. It’s available for both Mac and Windows.
- Download and install iTunes 9.2
- Connect your iPod Touch to your computer and using iTunes, upgrade to iOS 4. Do this the official way as described here.
- Now that you have iOS 4 final build on your iPod Touch, you’ll have to jailbreak it by using the iOS 4 GM build with redsn0w 0.9.5 Beta 5. Click browse and point it to iOS 4 firmware and follow the instructions on the screen. Remember to enable battery percentage, wallpapers and multitasking. [Vista users might need to run redsn0w as administrator]
One you’re done, your iPod Touch should reboot. Remember to add this repo to Cydia http://apt.saurik.com/cydia-3.7. Enjoy your newly jailbroken iPod Touch with iOS 4! Check out our quick start guide on the new features.

A few minutes is a lot. You might need to retry the whole process.
I've tried 3 times now, consecutively. Everytime I would try it, it would say it's finished, but on the iPod it would still be downloading Jailbreak data. So then, I would simply do the process all over again. Should I just keep trying?
just leave it alone. It will finish on it’s own.

On the iPod the process will take some time. Let it complete.
i keep getting stuck at the waiting for reboot screen. ive run redsnow probably ten times. its an ipod 2g. pc model. and im running on mac snow leopard.
In redsn0w, you can choose to not install Cydia while allowing multitasking and the wallpaper.
It'll technically be jailbroken, but since you're not installing anything from Cydia, it won' lead to crashes.
With a tethered jailbreak, every time you reboot the device you'll have to connect it to a computer and re-run the jailbreaking software else it either won't work or won't keep the jailbreak.
Untethered means you can reboot it all you want and it'll work fine.
my ipod's been stuck on a black screen for 5 minutes..what do I do?
same with me what should we do
y i cant add the repo?

Thank You
Does this redsn0w beta not work with itouch 2G MC-model? Whenever you browse for the IPSW and select it, a message asks if you have a MC model and says that the beta does not support MC models. If this is really true I would highly recommend putting this in your guide because i had previously jailbroken 3.1.3 and updated to 4.0 because i thought that this beta would work. Now it looks like there is no way for me to jailbreak iOS4
This happened to me too .
I decided to leave it on overnight . It worked in the morning . I guess it takes a REAALLLY long time to DL the packages . Make sure if you try this , to set auto-lock to never !
So did this actually work?? I'm very scared to try this since no one officially commented that this works.
i downloaded the official OS but red snow still doesn't specify it. :S help please?
this site has been very helpful to me .
it takes a while to load (i think this happans cos its gotta load all the links to the firmware files)

ultrasn0w has a Zero not an O.
You can jailbreak iOS4 using this guide.
Yes it works.
Have you downloaded the one for iPod Touch 2G ? The link to the downloads is given in the guide. Check again!
redsn0w 0.9.5b5-3 doesn't works with MC models of iPod touch 2G.
Does this work on MC models? Coz mine is an MC model and when they ask me if it is a MC model, i click yes, then i get an error and can no longer carry on the process? Help please??
Are you sure? I haven't heard any reports that it doesn't.
