Jailbreak iPhone? Tethered or Untethered?

This post is strictly for educational purposes only.

Is iPhone a need, trend or status? If you ask that question to your bf, be prepared that he will dump you.  Why? Guys just don’t like tough question. Don’t even attempt to ask him to choose between his mom and you. You, girls are just playing with fire.

Regardless whether it is a need, trend, or status, I just got my iPhone4 recently. Not to brag that I have an iPhone4 but my intention here is to capture the steps to jailbreak your phone so that you can save few hundred bucks just by DIY (more like for my own records too).

In case you are just out from the cave, this is iPhone4.

Firstly ask yourself before you even do it, what is jailbreak and why do you need it? If your answer is either i) to void the warranty, ii) to get free games and apps or iii) everybody do it,  then you are in right path.  

I am not sure about i) as some say that is a myth.  To me, my answer is none of above. I rarely play games on phone, I don’t follow what others do and more importantly I still want my warranty. All is simply because for the sake of curiosity and educational purposes. So, I decided to jailbreak the iPhone4.

Here is the Step 1: Check your phone version by clicking Setting > General > About .I am using iOS 4.2.1 for this examples

There are two options, tethered and untethered Jailbreak. Tethered jailbreak means you need to connect iPhone to computer each time it need to be booted to Jailbreak. While untethered jailbreak means the iPhone can be powered off and rebooted without affecting jailbreak without requiring iPhone to connect to computer.

Personally, I prefer untethered jailbreak because it is less hassles (good for lazy people like me).  Then you should download the jailbreak software from available website. I am using untethered jailbreak form greenpoisOn as an example.

Here is the Step 2: Download the jailbreak software that matches your computer operating system greenpoisOn. Unzip the file to your desktop once you finish downloading.

Here is the Step 3: Normally the iPhone4 will be auto sync when it is connecting to computer by using iTunes. To be on the safe side, back up again by right click your phone icon > backup  . This is to enable you to restore to original factory setting if something goes wrong.

Here is the Step 4: Disconnect iPhone4 from iTunes and computer after backing up and reconnect again. Close iTunes and do not unplug the USB cable until complete.

Here is the Step 5: Double click on greenpois0n.exe, click No as you are currently jailbreaking the iPhone4 not AppleTV.

Here is the Step 6: Click on “Prepare to Jailbreak (DFU)”

Here is the Step 7: Follow the screen instructions

Here is the Step 8: iPhone4 will boot the first time with verbose text on screen. This operation will install the jailbreak on the device. The device will reboot normally.

Here is the Step 9: Start the Loader application (green icon on the SpringBoard), and follow instructions to install Cydia.

Here is the Step 10: After installing Cydia, your iPhone is now load with untethered jailbreak.

INSTALLOUS

Is that all? Of course not. Jailbreak only work best if you have Installous. This is to teach you how to get free apps and games. Please note that this is only for educational purposes as I rarely play games on phone as I mentioned earlier.

STEP 1: Open Cydia and go to Manage section

STEP2: Go to Sources, Click Edit and then click Add.

STEP3: Type in cydia.hackulo.us

STEP4: Your iPhone4 will respring itself. You will see the Hackulo.us as a source after you press return in to Cydia. Click done.

Step 5: Now click on Hackulo.us , find Installous and click to install! Now your phone is installed with Installous.

Installous is like Apps Store where you can download games and apps in your iPhone4 with no charges. Without this, you can still purchase software that you like via Apps Store but it defeat the purpose of jailbreak in the first place right?

Theoretically, you are pro in jailbreaking iPhone now. Oh yea! The same method will be applied to jailbreak your iPhone, iPad, iTouch and AppleTV too.

Hope you find this educational material is useful especially when people are talking about jailbreak next time. 

* Jailbreak will not lose the pre-existing apps, setting or contacts. However, it is recommended to backup your phone first prior jailbreaking your phone. If you want to restore to original factory setting, please note that all the pre-existing apps, setting or contacts will be wiped off.
