What is jailbreak for iPhone, can anyone explain to me specifically, and how to jailbreak.

Jailbreak refers to the opening of the user's operation permissions, so that the user can erase the running status of any area at will, only after the jailbreak is successful, the iPhone's file system is in the read-write (RW) state, and third-party programs and plug-ins that have not been officially certified can be installed and run.

Jailbreak method, take jailbreak as an example:

1. Preparations:

Back up your device through Sync Assistant or iTunes (upgrade to the latest version), and then close the antivirus software and running programs to ensure that the device has sufficient power so that it does not affect the installation.

2. Start jailbreaking.

2) After entering the interface, click the browse button in the bottom left corner and click on the firmware.

3) Enter the interface and select only Install Cydia. If you are 3GS and choose the baseband of your iPad, you will also see a prompt like this, and if you upgrade, you must select "yes".

4) Once here, keep your iPhone connected to your computer.

5) Next, use the home button and the power button to operate, click the next button, the following interface appears, immediately press and hold the power button for 3 seconds, at this time the screen appears white apple.

6) When the second message appears, do not release the power button, and then press and hold the home button for 10 seconds. Wait for your iPhone to restart automatically.

7) Release only the power button, continue to hold the home button for 15 seconds, at this time, if it succeeds, it will jump to the next interface, and you can release the home button.

8) Jailbreak complete.

Jailbreaking is when there are some paid software in the App Store. That is, if you install iTunes on the PC side, the APP charging software in it must be charged, so there is no charging limit after jailbreaking (not directly you can go down to the paid software) Jailbreak is generally equipped with Cydia, and you can add software to it. Or there are software resources on Weifeng.com that can be added to your love madness.

Generally, jailbreak with Black Rain Blackra1N or Red Snow Redsn0W, depending on your firmware, if it is temporarily not perfect jailbreak. You can use the green rain limera1n to jailbreak the firmware. Just take a look at Wei Feng and find out.

Get system administrator permissions, that is, root permissions, so you can DIY the machine yourself, install third-party software and modify the system at will, but the risk is very easy to white apples and cause system instability, poisoning or something.

Jailbreaking refers to taking advantage of some vulnerabilities in the iOS system, obtaining root access to iOS through instructions, and then changing some programs to enhance the functions of the iPhone and break through the closed environment of the iPhone. When the iPhone was first bought, it was closed. As ordinary users, we can't get the root permission of iPhoneOS, let alone install some software into the phone by ourselves.

Jailbreaking refers to cracking Apple's mobile phone operating system, just like cracking the XP operating system is a truth.

To put it simply, change the American version to the Chinese version, so that the next software will not cost money!

If the iPhone 4S is successfully jailbroken, the future is bright, and this will become Apple's eternal because of the closed nature of Apple's ecosystem, and the programs developed after that can run perfectly on iOS.

Is jailbreak good? What are the benefits of jailbreaking?

The advantage of iPhone4S jailbreak is that you can use third-party software, to put it bluntly, you can use a lot of free software, because the high-quality software on the iPhone needs to be charged, in addition, iPhone4S can have more custom functions after jailbreaking, you can't install themes without jailbreaking, etc.!
