Jailbreak your iOS 5.0.1 with Redsn0w

Below is the complete step-by-step to jailbreak iOS 5.0.1 on iPhone, iPad, iPod touch.

Before we get started, please consider that:

    * The jailbreak doesn’t currently work on the iPad 2 nor the brand new iPhone 4S.
    * This is a tethered jailbreak, so whenever you need/feel compelled to reboot your iDevice, you will have to connect it to a PC or Mac running Redsn0w in order to jump-start it.
    * Finally, please consider that if and when the untethered jailbreak appears, you will have to start a fresh – you will not be able to simply ‘upgrade’ your jailbreak as it were.

So, hopefully you’re clear on the above, so let’s get jailbreaking!

Step 1: Download the latest version of iTunes (10.5) for Windows or Mac.

Step 2: Connect your iOS device to your PC or Mac and backup everything up. Although it’s a simple process, always better to be safe than sorry.

Step 3: Update to software version 5.0.1 Beta; download links of which can be legally found on iOS Dev Center only.

Step 4: Grab the latest version of Redsn0w, depending on your operating system, for Windows or Mac.

Step 5: Start Redsn0w. Click on “Extras”, and then click on “Select IPSW” option to manually select the final public version of iOS 5 (NOT iOS 5.0.1) for your device. Download links for iOS 5 can be found here.

Step 6: Now go back, and click on "Jailbreak", and opt to "Install Cydia". You will then be led through a sequence to place your device into DFU mode. Once your device has achieved DFU mode, Redsn0w will apply the jailbreak.

Booting Tethered:

Step 7: Once the Cydia installation is complete, you will need to boot the device into a tethered state in order for the jailbreak to work – something you will indeed be required to do every time you reboot. Enter DFU mode, and in "Extras", select "Just Boot".
