Jay Freeman (born November 27, 1981) 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 (where OS stands for operating system) that allows for the installation and customization of software outside of the regulation imposed by the App Store system.
Freeman studied and graduated with a degree in computer science from the College of Creative Studies at the University of California, Santa Barbara. In 2009, he was a doctoral student in computer science at UCSB.
He built Anakrino, a decompiler for .NET available in 2002. He co-authored a paper published in 2005 about a "Java runtime event specification and monitoring library." He has worked with Brian Fox on multiple freelance projects.
In February 2008, Freeman released the initial version of Cydia, a software distribution and installation tool for jailbroken iOS. In May 2009, he added a proprietary store system to Cydia which allows developers to sell their products. In September 2010, his company (SaurikIT, LLC) announced that it had acquired Rock Your Phone, Inc. (makers of Rock.app). SaurikIT and Rock Your Phone were the two largest providers of third party apps.
He has published tools for developers to make software, particularly for jailbroken iOS. He made Cydia Substrate, a framework that developers use to help them modify iOS with extensions. He also made Cycript, a tool that developers use to inspect and modify applications on iOS and OS X.
He has developed a plethora of software extensions for jailbroken iOS users to add features to iOS, including Apple File Conduit 2, Cycorder, CyDialer, Cydget, Cyntact, Cyueue, Five Icon Dock, Veency, and WinterBoard. He has also released Cydia Impactor for jailbroken iOS, a tool for removing personal data and "unjailbreaking" the device while preserving the iOS version.
He is also a member of the iPhone Dev Team group, which has developed jailbreaks for iOS.
