VLC was a free media player that supported file types that the iPhone’s media player doesn’t, including AVI, MPG and MKV. The free app, which appeared in October 2010, was based off the open-source desktop software of the same name. (Image from iDownloadBlog)
Violation: Apple isn’t directly responsible for this app’s removal. But because the App Store uses digital rights management, that put VLC in violation of its open source licensing agreement. A developer on the desktop project, Rémi Denis-Courmont, asked Apple to remove the app, and Apple yanked it last January.
Jailbreak Alternative: The app is still available through Cydia.
