Cydia Iphone

Cydia is a software application for iOS that is a graphical front end to APT and the dpkg package management system. It allows a user to browse and download applications for a jailbroken iPhone, iPod Touch or iPad. It was developed by Jay Freeman (also known as “saurik”). Cydia was originally released as an open-source alternative to Installer.app on iOS 1.1.x, but quickly became the most popular package manager upon 2.0′s release.

Cydia’s repositories allow the installation of software packages, most of which are available to download at no cost. Cydia also includes the Cydia Store, which offers a number of applications for sale. Software packages are downloaded directly to an iOS device, to the same location as Apple’s pre-installed applications (the /Applications directory).

The name “Cydia” is an allusion to the Codling Moth (“Cydia pomonella”), which made famous the “worm in the apple.”
