iOS 6.0.1 the firmware that was released today is already jailbreakable. Note that this jailbreak will have the same specifications as the previous one and only work for pre-A5 devices. In addition this jailbreak is still tethered for all devices other than old bootrom 3GS’s meaning that you will have to boot tethered every time your device shuts off.

Tethered
- iPhone 4
- iPhone 3GS new bootrom
- iPod Touch 4G
Untethered
- iPhone 3GS old bootrom [Does your device have an old bootrom?]

Tutorial for all A4 devices (Tethered)

1. Download and Install RedSn0w 0.9.15B2 or higher. [Download Link]
2. Download a copy of your device’s iOS 6.0 firmware. [Download Link]
3. Invoke DFU mode on your device, if you don’t know how to do this RedSn0w will walk you through it when needed.
4. Open Redsn0w, navigate to: Extras>Select IPSW and select your iOS 6.0 firmware that you downloaded in step 2.
5. Now navigate back to the home page of RedSn0w and click the ‘Jailbreak’ button. Leave this to continue until boxes come up and check ‘Install Cydia’.
6. Once done, your device will appear as if it has just booted. However Cydia will not be on your homepage. You now need to perform a tethered boot.
7. Connect your device back up to your computer if you have disconnected it, and reopen RedSn0w if you closed it. Now place your device one again into DFU mode, and go to Extras>Select IPSW and select the same firmware that we did in the first step, it’s essentially the same process. Once RedSn0w has done it’s thing, select ‘Just Boot’ and when your device reloads it will have Cydia on it!

Since the jailbreak is tethered you will have to complete step 7 every time your device fully powers down.

With the release of iOS 5 things have been very busy! This didn’t stop the iPhone Dev-Team from releasing an update for RedSn0w bringing RedSn0w to version 0.9.9b5. In this new version of RedSn0w (for Mac OS X users only at this time) you can Jailbreak iOS 5 in only a few clicks. Follow the how to guide below to Jailbreak tethered the iPhone 4 and iPhone 3GS running iOS 5 (official version) on Mac OS X.

Step 1: Download RedSn0w 0.9.9b5 for Mac OS X using the download mirror below

Step 2: Once you have downloaded RedSn0w version 0.9.9b5 you will need to launch it by double clicking on the redsn0w app.
Step 3: With RedSn0w up and running you will then click the Jailbreak button.
Step 4: Click the Next button and you will come to a screen where you will need to put your iPhone into DFU mode. Read through and follow the instructions presented to you which is to plug in and power off your iPhone and click the Next button.
Step 5: When you click the Next button you will need to follow the instructions presented to you to put your iPhone into DFU mode.

• Hold down Power (corner) button for 5 seconds.
• Without releasing the Power button, also hold down the Home (bottom center) button along with the Power button for 10 seconds.
• Without releasing the home button, stop holding down the power button for up to 15 seconds.

Step 6: After you successfully enter DFU mode RedSn0w 0.9.9b5 will now prepare the jailbreak data. Once RedSn0w is done ensure the “Install Cydia” option is checked and click the Next button.
Step 7: RedSn0w will begin jailbreaking your iPhone. DO NOT interrupt or use your Mac during this time. When your iPhone is finished being jailbroken it will reboot into a jailbroken state. Congratulations!
Optional: Booting Tethered - When you Jailbreak your iPhone running iOS 5 (official version) you will have a tethered Jailbreak. Meaning in order for your iPhone to turn back on you will need to boot it using RedSn0w (this applies every time your iPhone looses power). To do this launch RedSn0w again and click the Extras Button > then click the Just boot button and you will need to put your iPhone into DFU mode again.


Note: Yes, you need to do this every time your iPhone looses power.

Apple has unexpectedly pushed out an incremental update for iOS 4.3.x, and it is dubbed as iOS 4.3.5. This minor release is no more than a security update, aiming to patch issues with certificate verification.

The good news is that we have tested it and can confirm that the current version of Redsn0w can jailbreak the just released iOS 4.3.5 on iPhone 4, 3GS, iPad 1, and iPod touch 4G/3G. But it will be limited to tethered boot, which means you will have to reconnect your device to your computer every time you reboot your iOS device. iPad 2 is obviously not supported. This has also been confirmed by MuscleNerd of iPhone Dev Team:

@zaone @m1ckey29 ah ok thanks for checking! So those who really do want tethered 4.3.5 can use redsn0w pointed at 4.3.4 (except iPad2)

Note: Those relying on a carrier unlock must stay away from Redsn0w.
How to Jailbreak iOS 4.3.5 (Tethered)
Step 1: Download iOS 4.3.5 and iOS 4.3.4 (required by this version of Redsn0w) firmware file for your device from the links given at the end.
Step 2: Download Redsn0w 0.9.8b4 for Windows or Mac. Also make sure you are running the latest version of iTunes, which is version 10.4.
Step 3: Now start Redsn0w, browse for the iOS 4.3.4 firmware file (NOT the 4.3.5) that you downloaded in Step 1 and point it towards Redsn0w. Refer to the screenshots below:


Step 4: Once Redsn0w is done recognizing the firmware file, click Next and there you’ll be taken to a new window. Simply check the “Install Cydia” box as shown below and leave other options as it is for now. Once done, click Next.

Step 5: On this screen, Redsn0w will instruct you to power down your device and plug it in to your computer. Follow the onscreen instructions and then click Next to continue.

Step 6: On this screen you will have to put your device in DFU mode with a combination of the Power button and the Home button for a certain amount of time, simply follow the onscreen instructions on how to do so. The combination is usually like this:

• Hold down Power button for 5 seconds.
• Now without releasing the Power button, hold down the Home button simultaneously with the Power button for 10 seconds.
• Let go of the Power button but keep on holding the Home button for another 15 seconds.

If you performed the above mentioned steps correctly, then your device should be in DFU mode.

Step 7: Redsn0w will now jailbreak your device, don’t do anything weird at this point, just let Redsn0w finish. We would recommend that you don’t do anything with your PC or Mac at all during the process. Sitting idle and waiting for the process to end on its own is much advised.
Since this is a tethered jailbreak, therefore whenever your iOS device loses power, it will go into the dreaded Apple logo boot screen loop. To get out of that, simply start from Step 3 again and in Step 4, uncheck “Install Cydia” and instead check “Just boot tethered right now” option and hit “Next” with your iPhone, iPad or iPod touch connected to your PC or Mac. And yes, you will have to do this every time when your device reboots or loses power.

That’s it! You should now have a jailbroken iPhone, iPad, or iPod touch running iOS 4.3.5.
