越狱介绍

Jailbreaking is the process of

removing limitations on iOS, Apple's operating system, on devices running it through the use of software and hardware exploits; such devices include the iPhone, iPod touch, iPad, and second-generation Apple TV. Jailbreaking permits root access to the iOS file system and manager, allowing the download of additional applications, extensions, and themes that are unavailable through the official Apple App Store.

Jailbreaking is a form of privilege escalation, and the term has been used to describe privilege escalation on devices by other manufacturers as well.[3][4] The name refers to breaking the device out of its "jail",[5] which is a technical term used in Unix-style systems, for example in the term "FreeBSD jail". A jailbroken iPhone, iPod touch, or iPad running iOS can still use the App Store, iTunes, and other normal functions, such as making telephone calls. Restoring a device with iTunes removes the jailbreak.

released a fix for this security hole, jailbreak users had access to a fix published by the developer of JailbreakMe

When a device is booting, it loads Apple's

own kernel initially. The device must then be exploited and have the kernel patched each time it is turned on.

An "untethered" jailbreak has the property that if the user turns the device off and back on, the device will start up completely, and the kernel will be patched without the help of a computer – thus enabling the user to boot without the need to use a computer.[60] These jailbreaks are harder to make and take a lot of reverse engineering and years of experience.

With a "tethered" jailbreak, a computer is needed to turn the device on each time it is rebooted. If the device starts back up on its own, it will no longer have a patched kernel, and it may get stuck in a partially started state. By using a computer, the phone is essentially "re-jailbroken" (using the "boot tethered" feature of a jailbreaking tool) each time it is turned on.[61] With a tethered jailbreak, you can still

restart SpringBoard ("respring") on the device without needing to reboot.

There is also "semi-tethered" solution, which means that when the device boots, it will no longer have a patched kernel (so it will not be able to run modified code), but it will still be usable for normal functions such as making phone calls, or texting.[62] To use any features that require running modified code, the user must start the device with the help of the jailbreaking tool in order for it to start with a patched kernel (jailbroken).

?引导式越狱（Tethered Jailbreak），指的是当设备重启时之前的越狱就会失效，用户将失去Root权限，需要连接电脑来使用红雪（redsn0w）等越狱软件进行引导开机(即再次越狱），否则设备就无法开机使用。

?不完美越狱（Semi-tethered Jailbreak）最初源自引导式越狱的临时性修复，因此与引导式越狱一样定义为“在设备重启时之前的越狱就会失效，用户将失去Root权限”。

但区别在于重启后设备至少能作为未越狱设备正常使用。而若想要Root权限，则需再次越狱。

?完美越狱（Untethered Jailbreak），指的设备没有任何开机重启问题。

FullForce：

强制应用全屏运行的插件。我们都知道iPhone 的软件在iPad 上运行时是会以小窗口显示的，而不支持iPhone 5 的旧版iPhone 应用也会显示上下两条黑边。FullForce 可以让你指定某些应用强制以全屏的方式来运行，它不是简单的缩放画面，而是会自动去修改APP 界面上的一些元素（如列表的宽度和高度等）让其变得就像原生全屏应用一样。当然，并不是所有的软件都能完美支持，这个需要你亲自一一测试才能知道结果。FullForce 分为FullForce 和FullForce for Phone 两款插件，前者仅限iPad 使用，后者支持iPhone 5 以及iPod Touch 第五代，有全屏使用需求的同学可以去试试看。
