The iPhone Dev team releases a software utility called redsn0w for Mac and PC which you can use to jailbreak your iPhone, iPod touch, and iPad. Once you download, and run redsn0w it will optionally install Cydia on your device along with the jailbreak so you can install 3rd party apps. If you want to unlock your iPhone and use a non-supported carrier using redsn0w you will have to use the Extras feature and build a custom ipsw file. There are also others apps including ultrasn0w for unlocking your device. As of now the latest supported jailbreak using redsn0w is iOS 5.0.1 for all devices running the A4 chip. Jailbreaks for the iPhone 4S and iPad 2 with the A5 chip using redsn0w are coming soon.
What is tethered vs. untethered? Generally, an untethered jailbreak is the better option. A tethered jailbreak is less desirable, and should only be used if absolutely necessary. With a tethered jailbreak you will need to connect your device to your computer using the sync cable if you ever need to restart it or if the battery dies. Then while rebooting you will choose “just boot tethered” from the options.
How to jailbreak iOS 5.1 with redsn0w (semi-tethered)
This jailbreak works on all iOS devices with an A4 chip running the iOS 5.1 firmware. Not supported yet are: iPhone 4S, iPad 2 and iPad 3. Also note that this jailbreak is semi-tethered.
Run redsn0w while your device is connected to your computer
Click Jailbreak, turn off your device and put it into DFU mode using the instructions provided in Redsn0w.
Choose the “Install Cydia” and other optional items and continue
Wait while Redsn0w does its jailbreak which takes less than 10 minutes.
Now we need to redo a couple of steps to tether your device and get rid of the white Cydia icon. Re-open Redsn0w and go to the Extras section.
Choose “Just boot” and put your device into DFU mode once again and wait for a reboot. After this step your Cydia icon will be working.
To get a “semi-tethered” device do the following in Cydia
Go to the Manage tab > Sources > Edit > Add > type in this URL: http://www.thebigboss.org/semitether > Hit Add
Now go back to the source you just added, find the “semitether” application and hit Install.
Here’s a video demo showing you the above steps for installing Cydia on iOS 5.1 devices with an A4 chip.
How to jailbreak iOS 5.0.1 with redsn0w (untethered)
Fresh iOS 5.0.1 Use these steps if you have just upgraded to iOS 5.0.1 and have not tried to jailbreak before. If you need to unlock, read all the steps before you proceed.
Connect your device and open iTunes. Upgrade to the new 5.0.1 firmware. Keep your device connected to your computer.
Select the file you downloaded above and let redsn0w build a custom firmware for you.
Now go to Extras > Pwned DFU
Restore your device using the custom firmware in iTunes.
Now you can unlock your iPhone using Gevey SIM, or the updated Ultrasn0w.
Previously Tethered iOS 5.0.1 Jailbreak If you have jailbroken to a tethered iOS 5.0.1 before (as described in the steps below) then follow these simple steps.
Search for and install a new package called Corona 5.0.1 Untether
You will now convert your tethered jailbreak to an untethered jailbreak
Supported Devices with A4 chip
iPhone 4 (GSM)
iPhone 3GS
iPod touch 3G
iPod touch 4G
iPad 1
iPad 2 (not yet, coming soon)
AppleTV 2G (PwnageTool only for now)
Unsupported Devices with A5 chip
iPad 2
iPhone 4S
How to jailbreak iOS 5 with redsn0w (tethered)
Note: This is a tethered jailbreak. This means you will need to connect your device to a computer and use redsn0w as shown below in the last step, each time you want to reboot your device.
Tip If you’ve already upgraded to iOS 5 and have the latest iTunes software, you can jump to step 3.
Unlock notice: If you want to unlock your iPhone don’t upgrade to the latest iOS 5 via iTunes. Read the last step first for details.
Download and install iTunes 10.5 on your Mac or PC
Connect your device and open iTunes. Upgrade to the new 5.0 firmware. Keep your device connected to your computer.
Run redsn0w while your device is connected to your computer.
Click the Jailbreak button labelled: Jailbreak and Install Cydia. Good news! Starting with this release, redsnow just downloads the .ipsw file automatically from Apple for you. No more messing around with ipsw files.
Turn off your device and keep it connected to your computer, then click the Next button.
Follow the steps on the screen to put your device into DFU mode. Here’s how
Hold the power button for 2 seconds
Hold the home button without releasing the power button.
Release the power button but keep holding the home button until installation starts
Wait while the jailbreak completes. You’ll see a series of commands and screens on your device. After a few minutes this process will be complete, your device will restart and you will see the Cydia app icon on your HomeScreen.
Go into DFU mode, from the redsn0w Extras section pick Just Boot and redsn0w will boot your device as tethered.
Steps for Unlock user only
Don’t update to the latest iOS 5 version from iTunes.
Run redsn0w while your device is connected to your computer.
Click Browse and select the .ipsw file you downloaded from step 3. Wait while redsn0w processes & successfully identifies the IPSW file, then click the Next button.
Check the box for “Install Cydia” and click Next.
Turn off your device and keep it connected to your computer, then click the Next button.
Follow the steps on the screen to put your device into DFU mode. Here’s how
Hold the power button for 2 seconds
Hold the home button without releasing the power button.
Release the power button but keep holding the home button until installation starts
Wait while the jailbreak completes. You’ll see a series of commands and screens on your device. After a few minutes this process will be complete, your device will restart and you will see the Cydia app icon on your HomeScreen.
Here is a video demo of using redsn0w on the iPhone with Windows

Hi i was wondering what OS are u using, looks like vista but the wallpaper is very nice. If your using vista what kind of add on did u use to achieve that desktop ?
@Ando redsn0w will not unlock iPhone 3G, as it says above. you have to revert back to 2.2.1 or something for now and unlock using QuickPwn for now until ultrasn0w comes out
can i ask you something.? i foloow the instructions but i face one problem.. when i go to the file itunes show me 2 folders tha none of them call iphone software updates.. the one called iphone carrier suport and the other itunes plugs in.. and non of them show me the file i should browse.. if you can help me thnx
i have an iphone 3g that is unlocked. i used cedia to load a game which i later uninsalled. now i can only recieve calls, since all the menu items are lost. what can i do.
hey dude, why after download finished (iphone 2g), it cant be opened by redsn0w? i think because of the application format is not ipsw. right? and my question is, how can be opened? please help me mates.
Hey adlantagor, if you notice the file you download has an extention ipsw.zip All you need to do is delete the zip extention and leave it as .ipsw and that’s it.
I have the Ipod Touch 2G (2.2.1).
Using redsn0W 7.2 and it only stay at the hard drive picture for a long time then when it reboots, it asks me to connect to Itunes to restore the firmware.
Tried 4 times with no luck.
How can I upgrade to 3.0 and jailbreak the same time?
has anyone had problems with bluetooth on the redsn0w iPhone 2G 3.1.3 upgrade. Mine doesn’t seem to want to pair anymore.
Other problems:
my tmobile prepaid sim is the only one that “works” now. however, when i go to Sbux, my Vonage Mobile no longer works. I have to reset the network settings to get it to work at home.
my att gophone sim won’t work at all anymore.
at least I can make VOIP calls and prepaid calls, so I’m not complaining. but i had all of these features with blackra1n. do you think redsn0w will release a patch or update? anyone know of fixes on cydia that i can try?
same safari download problem with a software called “appsnap” or “installer.app”. people say u gotta download straight on the iPod and from a site called “jailbreakme.com”
and another problem is that, that site has absolutely nothing related to appsnapp or installer.app. ( no links. nothing…)
I try looking for every jailbreak software from every site possible but no luck. pls help
quicknight, by going to jailbreakme.com i’m also directed to “the conceited store” but there’s absolutely nothing there.
if u type jailbreakme.com in YouTube, you’ll see vids of people visiting that same site on their iPods but it looks totaly different.
