How to Jailbreak 4.3.3 iOS on the iPhone 4 and iPod Touch

This article will give you a step-by-step guide on how to jailbreak not only the iPhone 4, but also almost any Apple device running on 4.3.3 iOS. Technically speaking, jailbreaking removes the limitations Apple places on its products. Practically speaking, jailbreaking allows you to get free applications, moving backgrounds, and many more modifications and "tweaks" on your device. However, the process will void the warranty on your device, and may make your device slightly slower. By following these instructions and navigating through each step successfully, you will be able to jailbreak any 4.3.3.3 iOS Apple device.

Jailbreaking Your Apple Device

Step 1: First, on your iPhone or iPod Touch, go to “Settings” > “General” > “About.” Confirm that under “Version,” it says “4.3.3.” If your Apple device says something else, you have an alternate version, and this method may not work. Then plug the device into your computer using a USB cord. iTunes may or may not open automatically. If it does, make sure not to download any updates onto your device, but if it doesn’t, open iTunes manually.

Step 2: Next, you need to download two items: Redsn0w and the new firmware you will be putting on your device. (Redsn0w is the software that helps you to jailbreak and firmware is the small amount of basic programming that structures an electronic instrument). To download both of these, see the following link: http://tysiphonehelp.com/home/2011/5/6/untethered-433-jailbreak-iphone-4-3gs-ipod-touch-3g-4g-ipad.html

Step 3: When you have the link above opened, look under the heading “4.3.3 Firmware.” Click on the device you plan to jailbreak to ensure you download the correct software. Scroll further down the page to the download links for Redsn0w and click either on the link for Windows or Macintosh, depending on which operating system your computer is running. Save both these files to your computer’s desktop.

Step 4: After you’ve opened the download link, open Redsn0w and click “Browse.” Locate the firmware that was downloaded to the desktop in Step 2 and then click “Next.” Make sure that the box next to “Install Cydia” is checked. I would recommend also checking “Enable Battery Percentage” but that step is optional. Enabling the battery percentage will allow you to view the amount of battery remaining as a number, instead of a partially filled outline of a battery.

Step 5: Make sure that your device is turned OFF but is still plugged into the computer. Do not turn your device on, and then plug it into the computer. Make sure to plug in your device first, and then turn it off. There are practically no risks in jailbreaking your device, but just in case you can’t access normal apps from the Apple marketplace or just want to revert back to a non-jailbroken state, you can always just plug in your iPod to the computer and click restore on iTunes.

Step 6: On Redsn0w, hit the “Next” button. Now you must put your device into DFU mode. This can be a little tricky but should only take a couple attempts at the most. I’m sure that by now almost everyone is familiar with the buttons on your iPhone or iPod touch, but just as a reminder, the circular button below the screen of the device is the “Home” button, and the small rectangular button on the top edge of the device is the “Power” button. When you click "next" on Redsn0w, the program will guide you through the process of putting your iPhone or iPod touch into DFU mode. You will need to hold down the power button for three seconds. Finally, while still pressing the “Power” button, simultaneously begin holding down the “Home” button. Count to ten seconds before releasing the “Power” button, but keep pressing the “Home” button for another 30 seconds.

Congratulations! You have just jailbroken Apple device. Before you worry about legal repercussions, know that jailbreaking is legal in the United States. The only serious negative effect from the procedure is that Apple reserves the right to void your warranty if they discover you have jailbroken your device. Battery life and system stability may be affected slightly, but batteries can be replaced easily, and you can always restore your device back to default settings. Enjoy your newfound electronic freedom!
