Installation of a computer program, is the act of making the program ready for execution. Installation refers to the particular configuration of software or hardware with a view to making it usable with the computer. A soft or digital copy of the piece of software (program) is needed to install it. There are different processes of installing a piece of software (program). Because the process varies for each program and each computer, programs often come with an installer, a specialised program responsible for doing whatever is needed for the installation. Installation may be part of a larger software deployment process.
Privilege escalation is the act of exploiting a bug, a design flaw, or a configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user. The result is that an application with more privileges than intended by the application developer or system administrator can perform unauthorized actions.
Mobile app development is the act or process by which a mobile app is developed for one or more mobile devices, which can include personal digital assistants (PDA), enterprise digital assistants (EDA), or mobile phones. Such software applications are specifically designed to run on mobile devices, taking numerous hardware constraints into consideration. Common constraints include CPU architecture and speeds, available memory (RAM), limited data storage capacities, and considerable variation in displays and input methods. These applications can be pre-installed on phones during manufacturing or delivered as web applications, using server-side or client-side processing to provide an "application-like" experience within a web browser.
The iPod Touch is a discontinued line of iOS-based mobile devices designed and marketed by Apple Inc. with a touchscreen-controlled user interface. As with other iPod models, the iPod Touch can be used as a portable media player and a handheld gaming device, but can also be used as a digital camera, a web browser, for email and messaging. It is nearly identical in design to the iPhone, and can run most iPhone third-party apps from the App Store, but it connects to the Internet only through Wi-Fi and uses no cellular network data, as it lacks a cellular modem.
iOS is a mobile operating system developed by Apple Inc. exclusively for its smartphones. It was unveiled in January 2007 for the first-generation iPhone, launched in June 2007.
SpringBoard is the standard application that manages the iPhone's home screen. Other tasks include starting WindowServer, launching and bootstrapping applications and setting some of the device's settings on startup.
On Apple devices running iOS and iOS-based operating systems, jailbreaking is the use of a privilege escalation exploit to remove software restrictions imposed by the manufacturer. Typically it is done through a series of kernel patches. A jailbroken device permits root access within the operating system and provides the right to install software unavailable through the App Store. Different devices and versions are exploited with a variety of tools. Apple views jailbreaking as a violation of the end-user license agreement and strongly cautions device owners not to try to achieve root access through the exploitation of vulnerabilities.
Cydia is a graphical user interface of APT for iOS. It enables a user to find and install software not authorized by Apple on jailbroken iPhones, iPads and iPod Touch devices. It also refers to the digital distribution platform for software on iOS accessed through Cydia software. Most of the software packages available through Cydia are free of charge, although some require purchasing.
Installer.app was a freeware software installer for the iPhone created by Nullriver and later maintained by RipDev, first released in summer 2007 and maintained until summer 2009. Installer allowed users to install third-party applications into the iPhone's Applications directory where native applications are kept. Users could install applications from a variety of sources provided by software developers or directly onto the iPhone without requiring a computer. Users could browse lists of applications inside Installer to find ones they wanted to install. In June 2009, RipDev dropped support for Installer in favor of developing a different package manager and installer named Icy.
Rooting is the process by which users of Android devices can attain privileged control over various subsystems of the device, usually smartphones and tablets. Because Android is based on a modified version of the Linux kernel, rooting an Android device gives similar access to administrative (superuser) permissions as on Linux or any other Unix-like operating system such as FreeBSD or macOS.
Jay Ryan Freeman is an American businessman and software engineer. He is known for creating the Cydia software application and related software for jailbroken iOS—a modified version of Apple's iOS that allows for the installation and customization of software outside of the regulation imposed by the App Store system.
In computing, a SHSH blob is a digital signature that Apple generates and uses to control the iOS versions that users can install on their iOS devices generally only allowing the newest iOS version to be installable. Apple's public name for this process is System Software Authorization. The term “SHSH blob” is unofficial and based on abbreviations for signed hash and binary large object. An alternative term, ECID SHSH, refers to the device's ECID, a unique identification number embedded in its hardware)
JailbreakMe is a series of jailbreaks for Apple's iOS mobile operating system that took advantage of flaws in the Safari browser on the device, providing an immediate one-step jailbreak, unlike more common jailbreaks, such as Blackra1n and redsn0w, that require plugging the device into a computer and running the jailbreaking software from the desktop. JailbreakMe included Cydia, a package management interface that serves as an alternative to the App Store. Although it does not support modern devices, it can still be used and the site is up.
Sideloading describes the process of transferring files between two local devices, in particular between a personal computer and a mobile device such as a mobile phone, smartphone, PDA, tablet, portable media player or e-reader.
An app store, also called an app marketplace or app catalog, is a type of digital distribution platform for computer software called applications, often in a mobile context. Apps provide a specific set of functions which, by definition, do not include the running of the computer itself. Complex software designed for use on a personal computer, for example, may have a related app designed for use on a mobile device. Today apps are normally designed to run on a specific operating system—such as the contemporary iOS, macOS, Windows, Linux or Android—but in the past mobile carriers had their own portals for apps and related media content.
iPhone OS 2 is the second major release of the iOS mobile operating system developed by Apple Inc., being the successor to iPhone OS 1. It was the first version of iOS to support third-party applications via the App Store. iPhone OS 2.2.1 is the final version of iPhone OS 2. It was succeeded by iPhone OS 3 on June 17, 2009.
The Pangu Team, is a Chinese programming team in the iOS community that developed the Pangu jailbreaking tools. These are tools that assist users in bypassing device restrictions and enabling root access to the iOS operating system. This permits the user to install applications and customizations typically unavailable through the official iOS App Store.
AppValley is an independent American digital distribution service operated and trademarked by AppValley LLC. It serves as an alternative app store for the iOS mobile operating system, which allows users to download applications that are not available on the App Store, most commonly tweaked "++" apps, jailbreak apps, and apps including paid apps on the app store.
