When Apple released its first iPhone, the device came without the App Store, as the company believed most third-party software should run through the built-in Safari browser. It didn't take long for developers to build third-party app stores, such as Installer.app and Cydia, which weren't under Apple's control. Things have evolved since then, with the official App Store being the go-to marketplace for iPhone users looking to install an application.
