Jailbreaking is the process that allows users to modify the operating systems of Apple® iPhones, iPods and iPads. A jailbroken phone or other device gives the user access to the root file system of the device, which is otherwise forbidden by the native operating system. Access to the root opens up a myriad of opportunities to install third-party cell phone applications and to customize and control the graphic interface of the device. Jailbreaking a phone or other device is not without risks, however. It voids the manufacturer's warranty, makes the device susceptible to malicious applications and brings with it the risk of ruining the device's file system.
The first iPhone was released in 2007 and was hailed as a marvel of smart computing and cell phone technology. Independent-minded developers and geeks, however, chafed at the inherent limitations of the device. For example, Apple® strictly manages applications, or apps, for the device and enforces various usage restrictions. The developers sought to take advantage of vulnerabilities in the operating system to allow them complete control over the device. The first jailbroken phone was created in July 2007, one month after the release of the first iPhone.
A jailbroken phone offers many benefits. The process grants the user complete access to the root file directory of the device, allowing him or her to manage files and make customizations within programs. The user also can modify the graphic interface, or the visual and functional applications for the device. Jailbroken phones might avoid expensive data roaming charges when visiting foreign countries. The user unlocks the jailbroken phone, inserts a pay-as-you-go Subscriber Identity Module, also called a SIM card, and enjoys largely reduced cell phone rates.
The jailbroken phone or device can be loaded with third-party apps even if they have not been approved by Apple®, which has stringent and sometimes controversial standards of approval no matter how useful or popular an app might be. Owners of jailbroken phones often feel that the devices are truly their own, rather than devices maintained under the strict control of Apple®. Jailbreaking does not modify the native hardware in the cell phone or electronic device, so a jailbroken phone can be easily restored to the original operating system.
There are risks in jailbroking a phone, however. The identity and intent of the developer of the jailbreaking software might be completely unknown. The software could ruin the device or unwittingly transmit personal data without permission, with no accountability or guarantee from the developer. Third-party applications that are poorly designed could drain the battery, cause device instability or accidentally or purposely inject malicious software or spyware into the device. Jailbreaking voids the manufacturer warranty, so if a jailbreaking process goes awry or the phone or electronic device is defective, the device becomes essentially useless.
