The revolutionary new iPhone/iPod Touch operating system, iOS 4, has been successfully jailbroken using Redsn0w. Here’s how:
1. Download Redsn0w for Mac OS X or for Windows
2. Connect your device to your computer and shut it off (slide to shut down)
3. Download the corresponding iOS 4 firmware for your iDevice from the “Downloads” section of TechGeec.com
4. Open Redsn0w and browse for the firmware that you downloaded. Select “Next”
5. Select which features you’d like to be installed with the jailbreak (certain devices cannot have multitasking, homescreen wallpaper, or battery percentage so enabling those features gives that device the features)
6. Click “Next” twice and prepare to put your iDevice into DFU Mode
7. On the screen that shows you what to do to put your device in Recovery Mode:
Hold power button for 3 seconds
While still holding the power button, hold the home button for 10 seconds
While still holding the home button, release the power button and continue holding the home button for 30 seconds
8. Congratulations! Once your device reboots you should have Cydia on your home screen.

I finally figured out what was wrong, keep up the great work i believe i talk for everybody when i say thank you for what you are doing.
I have the iPhone 3GS, and I got to download the iPhone 3GS firmware (4.0/8A293) then I go to use it and get a message saying unable to recolonize specified IPSW? Can someone help me out :(
The reason why you're getting that, is because FOR NOW, this jailbreak is ONLY for the iPhone 3G and iPod touch 2G. Redsn0w will be updated soon, however, to accomodate for the other iDevices.
oh ok hope it comes out soon my phone feels weird without my cydia lol Thanks for responding…
welll their is a promblem w this jailbreak my model is a MC :( model its not support will it be fixed? sometime sooner thank you
You can now jailbreak the MC model using PwnageTool. Read this: http://blog.iphone-dev.org/post/726179754/foursom…
i have the ipod 2g and its the new boot ram probaly … thanks for helping out tho i hope their a release soon
i don`t quite understand what is in there http://blog.iphone-dev.org/post/726179754/foursom… and i am using windows 7 and windows xp..
PwnageTool is for MAC ONLY and it will only jailbreak the iPhone 3GS and iPod touch 2G (non-MC models).
Is there any other programs that can jailbreak a iPod Touch 3rd gen 4.0 MC Model?
As of now, no.
im using windows vista… does redsnow jailbreak a 2g ipod touch MC model?
Hi !! I have 3GS firmware (4.0/8A293).
Can i roll back OR downgrade to 3.1.3 or lower firmware ??
How ??
You can downgrade ONLY if you've backed up your SHSH blobs. If you don't know what those are, you haven't done it and so you can't downgrade… you're stuck. If you have, you can download the firmware you want to downgrade to from the "Downloads" page here on TechGeec.com and then when you go into iTunes, put your iPhone into DFU/Recovery mode, and then on the summary page in iTunes where it tells you info about your device, hold the SHIFT key (PC) or the Option key (Mac) on the keyboard while clicking the "Restore" button in iTunes. A window will pop up and you'll need to select the firmware you downloaded from wherever you saved it to. After that, it'll restore to that firmware.
How safe is this? I'm new with jailbreaking and this would be my first time to do it if i push through… :D
Very Safe.
