iOS5 Untethered Jailbreak

So last night, after months of not having had a jailbroken phone (since the update to iOS 5) I took the step to jailbreak the phone. The motivation behind this was the release of the untethered jailbreak this week, courtesy of the iPhone-Dev team and @pod2g.

Supported devices are:

• iPhone 4 (GSM – CDMA)
• iPhone 3GS
• iPod touch 4G
• iPod touch 3G
• iPad 1

It was not without some issues.

There are some steps you need to take before you begin:

1. First off, to jailbreak the phone, you need to download Redsn0w ver. 0.9.10b3 for Windows or for Mac
2. Download the IPSW for iOS 5.0.1 for your specific device. This page has a list of IPSW’s for the different models.
3. Make sure you have the latest version of iTunes.
4. Make sure you are on the 5.0.1 version of the iOS. (Settings->General->About->Version
5. BACKUP YOUR PHONE

Now that you have all of the items you need, here’s a step-by-step guide:

1. Connect your device to the computer you have it partnered with and hold the power key down until the slider to shutdown the device.
2. Launch Redsn0w
3. Click on Extras->Select IPSW->Select the one you want.
4. Go back to the main screen and click the Jailbreak button
5. Make sure the “Install Cydia” box is ticked
6. Click Next
7. Make sure your device is bot turned off and plugged into your computer before you get to the next step
8. At the next step, you need to put the device in DFU mode. Follow the steps on screen.
9. Once this is complete (it takes a bit of time), you will see a Cydia icon on the screen. Congratulations! You are now the proud owner of a jailbroken phone.
