Users could install applications from a variety of sources (over Wi-Fi or UMTS) provided by software developers or directly onto the iPhone without requiring a computer.

Therefore, Installer 3 wasn't available for 2.0 and the vast majority of users switched to Cydia.

In May 2011, a team of developers called Infini-Dev recreated Installer 4 so that it could be run on iOS 4 and above, although the main current repositories are only compatible with Cydia and no longer compatible with Installer.

[citation needed] Infini-Dev took over after a while and moved the project under the AppTapp Team name.

A public beta was released on July 3, 2019, and it officially launched on January 15, 2020.
