What Is iOS Jailbreaking?

Jailbreaking originally means prison escaping. Nowadays it has an expanded meaning in iOS jailbreaking which is the process of removing the limitations imposed by Apple on devices running the iOS through the use of hardware/software exploits, such as iPhone, iPod touch, iPad, and second generation Apple TV,etc. Jailbreaking allows iOS users to gain root access to the operating system, allowing them to download additional applications, extensions, and themes unavailable on the official Apple App Store. The name refers to breaking the device out of its “jail”, which is a technical term used in Unix-style systems. A jailbroken iPhone, iPod touch, or iPad running iOS can still use the App Store, iTunes, and other normal functions.

Jailbreaking is necessary if the user intends to run software not authorized by Apple. Under the Digital Millennium Copyright Act, although Apple has announced that the practice “can violate the warranty”, jailbreaking iPhones is legal in the United States.

Advantages and disadvantages for jailbreaking
1. Expanding the feature set limited by Apple and Apple App Store.
Most jailbreaking tools automatically install Cydia, a native iOS APT client used for finding and installing software for jailbroken iOS devices. Users install these programs for purposes including personalization and customization of the interface, adding desired features and fixing annoyances, and making development work on the device easier
2. Use of handset on multiple networks
Jailbreaking also opens the possibility for using software to unofficially unlock iPhones so that they can be used with other devices. Software-based unlocks have been available since several years ago, with each tool applying to a specific iPhone model and baseband version (or multiple models and versions).
3. Censorship
Some users look for software beyond the App Store to express opposition to Apple’s censorship of content through the app approval process. For example, in early 2010, Apple banned an app submitted by Pulitzer Prize-winning cartoonist, Mark Fiore, because it “ridiculed public figures”, in violation of Section 3.3.14 of the iPhone Developer Program License Agreement. Apple later called Fiore and asked him to resubmit his app for approval. In late 2010, Apple banned the use of apps that allowed users to donate money to non-profit organization and charities. Apple also banned a WikiLeaks app, stating it “violated their developer guidelines”). As the list of banned apps continues to grow, some users have found jailbreaking to be a viable alternative to Apple’s censorship of content.
4. Shortcoming
Installing software published beyond the App Store has the potential to affect battery life and system stability if the software is poorly optimized or frequently uses resource-draining services (such as 3G or Wi-Fi).
