越狱
释义 DEFINITION
基本含义：原指囚犯非法逃离监狱的行为。在当代互联网语境中，特指通过技术手段解除苹果iOS系统的使用限制。
技术延伸义（主流用法）：指通过破解手段获得iOS设备的root权限，允许安装未经App Store审核的第三方应用、修改系统界面等功能。根据Statista数据，2021年全球约有7.2%的iPhone用户进行过越狱操作。
词源故事 ETYMOLOGY
2007年第一代iPhone发布时，苹果封闭的iOS系统催生了越狱需求。开发者George Hotz（网名geohot）在2007年8月发布首个iPhone基带破解工具，标志着现代越狱文化的开端。
技术演变分为三个阶段：
- 硬件破解期（2007-2009）：需要连接电脑刷机
- 网页越狱时代（2010）：JailbreakMe工具实现浏览器一键越狱
- 半开放时代（2013至今）：Cydia商店等平台规范化越狱插件的分发
典型案例：2020年unc0ver团队发布的越狱工具支持iOS 13.5系统，首周下载量突破200万次。用户通过越狱主要实现：
- 安装EmuElec等模拟器游戏平台
- 使用Kodi媒体中心软件
- 自定义控制中心布局
例句：'我的iPhone 12越狱后终于能用第三方主题了，不过Apple Pay功能会失效。'
DEFINITION
Literal meaning: The illegal escape of prisoners from confinement. In tech context, it refers to removing software restrictions on Apple devices through hacking.
Modern tech definition (primary usage): The process of bypassing iOS restrictions to gain root access, enabling installation of unauthorized apps and system modifications. Notably practiced by 7.2% of iPhone users globally in 2021 according to Statista.
ETYMOLOGY
When the original iPhone launched in 2007, Apple's walled-garden iOS system sparked the jailbreaking movement. George Hotz (aka geohot) released the first iPhone baseband exploit in August 2007, initiating modern jailbreak culture.
Evolution occurred in three phases:
- Hardware hacking era (2007-2009): Required computer tethering
- Web-based jailbreaking (2010): JailbreakMe enabled one-click browser exploits
- Semi-open era (2013-present): Platforms like Cydia Store standardized tweak distribution
Landmark case: The unc0ver team's 2020 jailbreak for iOS 13.5 garnered 2 million downloads in its first week. Typical user motivations include:
- Installing emulators like EmuElec
- Using media centers like Kodi
- Customizing control center layouts
Sample usage: 'Jailbreaking my iPhone 12 finally allowed third-party themes, though it disabled Apple Pay functionality.'
