Gtkpod was a graphical user interface designed for Linux and other Unix operating systems that enabled users to transfer audio files onto their iPod Classic, iPod Nano, iPod Shuffle, iPod Photo, or iPod Mini music players. Although it did not support some of the more advanced features of iTunes, gtkpod still performed the role of an iPod manager for Linux. Album art and videos were supported, and preliminary support for jailbroken iPhones and iPod Touches was also available.
