The highly anticipated iOS5 was released for the iPhone 4. This is the first major release version that had a working jailbreak from day one. Check out the video I made on how to jailbreak the iPhone. In the video, you get to see the easiest method I came up with to put the iPhone into DFU mode.

You’ll need a copy of RedSn0w version 0.9.9b5 or later. I like to download from iClarified:

Here is my steps to easily put the iPhone into DFU mode.

Easy iPhone DFU mode:

  1. Have the iPhone connected to the computer and turned on.
  2. Hold down the Home button and Sleep button at the same time. Keep both buttons held down until the phone turns off.
  3. As soon as the phone turns off, count to 6 alligators. (Basically, 6-7 seconds) Then release the Sleep button (top button). Make sure you continue to keep the Home button held down.
  4. That’s it. Redsn0w will automatically detects when the iPhone has entered DFU mode. Once you see that has happened, you can release the home button at your leisure. Remember, successfully entering DFU mode means the screen will be blank/off.

Here’s the video clip of the entire jailbreaking operation. You can watch it in 1080p high res. Hope this helps you figure out the process.
