Why you should Jailbreak and Unlock your iphone and how?

Updated on June 22, 2011

Do it easily and free!

When I thought of writing this hub, I first did a search on Hubpages to see if there are any good hub out there on this matter so far, but I hardly found something. I know this subject has been discussed millions of time on the internet, but at the same time millions of misleading, scam and bogus information also available on the internet. And people are being repeatedly scammed and ripped-off their money by promising a jailbreaking and unlocking software or service. Also people cheated and end-up paying $$ to $$$ for jailbreaking/unlocking their phone and the reality is all those information and software are already available freely on the internet!!

Disclaimer: The details outlined here is for educational purpose only and I urge you to check and follow the laws and regulation respect your country time to time on this regard. I will not be responsible for any kind of damage/lose caused to anyone by following/practicing these steps.

What is Jailbreaking and Unlocking and why (most of you already know the answer) ?

Well, you have to Jailbreak your iPhone if you want to remove the restrictions to install 1000s of other great third party applications – both free and paid. Without jailbreaking your phone, you are limited to use only Apple approved applications which is sold through iStore (Apple’s online store to buy applications for Apple’s devices)

And Unlocking is the process of removing the phone carrier restriction, so that you can use any SIM card of your choice in the phone. For example if you buy an iPhone from US it will be either locked to AT&T or Verizon and if you want to use it with T mobile, you have to unlock your phone.

And the main point, you have to Jailbreak your iPhone in order to unlock this. Why? Because you have to jailbreak your iPhone to install the unlocking software :-)

There are both Hardware and Software unlocks available and here we are discussing software unlock only, which is fairly very easy, no/less risky and famous.

Is jailbreaking and unlocking illegal?

As per the latest law, No. You can read more about this here

Is jailbreaking and unlocking safe?

It is safe with very minimal risk. If something went wrong you can always restore back to your factory settings. I request you to take a backup of your iPhone from iTunes before proceeding with jailbreak.

How to Jailbreak

Before we see this, you should understand different versions of iOS (probably you already know this). iOS is the operating system software available in your iPhone to manage all the operations of your phone (firmware). We have to use different versions and types of jailbreaking and unlocking software depends on the iOS versions and iPhone versions (iPhone first version, iphone3g, iPhone 3gs and iphone4). So here we are discussing how to jailbreak your iPhone 4 with iOS 4.3.3.

Don’t worry if your iPhone not in this version and type, the concept, steps and procedures are almost same for all versions and devices except the difference in the version of jailbreaking and unlocking software. In the last section I have given a table which can be used to find corresponding jailbreaking/unlocking software for your iPhone depends on its iOS version and type. Then you can Google the same and easily find a detailed tutorial on this. (Or let me know I can write another guide for your iPhone :-))

All credits and thanks go to iPhone Dev team for developing this software and helping everyone.

Before we proceed, it is recommended to take a backup of your iPhone from your iTunes and in worst case you can restore back to your original software. Also be warned that jailbreaking your iPhone will waive your Apple warranty; however you can restore back to your original iPhone firmware later if required.

Jailbreaking your iPhone 4 with iOS 4.3.3

To jailbreak we need the software called RedSn0w. And also we need to download latest iOS firmware from Apple website. The RedSn0w application will be used to patch this iOS firmware and then will be installed in your iPhone – installing firmware in your iPhone is also called Flashing. Then you are done!

Steps:

  1. Ensure that your iPhone has iOS 4.3.3 software and your iTunes has been updated to latest available version.
  2. Download RedSn0w 0.9rc15 available here: Windows Version MAC Version and unzip the file.(Here we are discussion about Windows version, but there is not much difference between Windows and MAC versions)
  3. Download latest iOS 4.3.3 firmware from here
  4. Create a folder on your desktop called 'iphone_unlock' and copy the downloaded firmware in to this folder.
  5. Open redsn0w.exe (double click) which is downloaded in step 2. Browse for the .ipsw firmware from the folder 'iphone_unlock' which we downloaded in the Step 3.

6. You will be asked if your phone is new model, read the explanation and select yes or no. Click next to continue.

7. Now it will take a few seconds before you present with other window with several options. ('Preparing Jailbreak Data' window with progress bar will be displayed at this time) Make sure to select install Cydia. You may also select other options like custom boot logo etc. Click Next to continue.

8, Plug your iPhone in to the computer and make sure it is OFF. Click next button

9. Now the redSn0w will guide you through the steps to get into DFU mode. Follow the instructions carefully.

10. If you have followed the instructions properly and successfully entered DFU mode, the RedSn0w will start jailbreaking your iPhone. You will see many codes and messages running through your iPhone screen, wait patiently till it complete. Once all done your iPhone will re-boot.

11. After re-boot you can see the application – Cydia on your iPhone springboard. You done! Your phone is now jailbroken and Cydia is your door to the 1000s of third party applications. Enjoy!

What is Cydia?

Cydia is an iPhone application that will help you to browse and download many third party iPhone applications for your jailborken iPhone.

Unlocking your iPhone 4 with iOS 4.3.3

Once you successfully jailborken your iPhone, it is very easy to unlock. We use UltraSn0w for the same. Again, thanks to iPhone Dev team for this wonderful software.

This unlock will work only with iPhone 4 iOS 4.3.3 baseband 1.59.00. If your baseband is different from above, this unlock will not work for time being. But there are some workaround for this, if you search “PwnageTool” and “preserve the baseband” on internet you will get some idea on this.

Steps:

  1. Make sure you have baseband 1.59.00 (Can be checked from your iPhone settings.)
  2. In your iPhone, go to Cydia and browse for UltraSn0w. Download and install the application.
  3. Reboot your phone. Done, your iPhone should now be unlocked. If you use T-mobile, turn 3G OFF in your iPhone settings.

      myi4u, thanks for your comment.

      I would jailbreak an iDevice only if it is really required.

      Great hub! I am still deciding whether or not to jailbreak my wife's iPhone 4. She is quite satisfy with the current setup and I am afraid that it will mess up her way of operating iPhone if it is jailbroken. At the moment, I am just leaving it as it is until she complains!

      Very nice hub, it's funny how apple gained many ideas for future versions of iOS from the jailbreaking community, even though they don't condone it, like folders for example.

      Thanks RedmanB.

      Yes, but people will continue to jailbreak until Apple allow them to install third party applications on their devices. However tie-up with more companies will help to reduce unlocking.

      Thank you for the guide! Hopefully more companies get rights to the iPhone, and jailbreaking ceases to become necessary.
