Jailbreaking, in a nutshell, frees your iPhone from limitations put on it by Apple and by the device’s carrier be it AT&T, Sprint or Verizon. While  it has been made legal, jailbreaking will void your warranty so keep that in mind before you take the plunge.

You’ll also want to read up on some reasons why you might not want to jailbreak.
Redsn0w 0.9.10b8b, the jailbreak tool that you’ll be using, is a tethered jailbreak. This means that you will have to connect your device to a computer that is running the jailbreak ever single time you want to power it up.
An untethered jailbreak is in the works but its release date is currently unknown.
With that, let’s move on to how to jailbreak iOS 5.1.1 for iPhone 4, iPhone 3GS, iPad, and iPod touch.

1. Install the latest version of iTunes.
2. Connect your iDevice to your computer and back up your files. Or, if you have iCloud enabled, you can check in your iCloud settings to see if the device has recently been backed up.
3. Download the correct version of iOS 5.1.1. You can do that Over-the-Air, by syncing your iDevice to your computer or by installing it manually.
4. Download Redsn0w 0.9.10b8b for Windows or for Mac.
5. As MuscleNerd points out, you’ll want to download the correct iOS 5.1 IPSW file for your device. You can find that here. Scroll down to the bottom and check Historical.
6. Run Redsn0w and once it’s open there should be an option for ‘Extras’. You’ll then want to choose the ‘Select IPSW’ option from that screen.
7. Select the iOS 5.1 file that you downloaded in step 5.
8. Then, in Redsn02, select ‘Jailbreak’ then ‘Install Cydia’. It’ll take you to DFU mode and Redsn0w will jailbreak your device and put it into DFU mode.
9. Pick ‘Just Boot’.
10. Enjoy a jailbroken iPhone.

Once you have done all of that, your device should be jailbroken. Because this is a tethered jailbreak, you’re going to have to go into Redsn0w to boot up the jailbreak every single time your device gets turned off, but it’s a small price to pay to have jailbreak access on day one.
And. as always, be careful. Especially those of you trying this for the first time.
