It is described by Apple this way:
Robert Berry's comic adaptation of the 1922 edition of James Joyce's epic novel, ULYSSES accompanied by a page-by-page reader's guide, dramatis personae, and pop-up translations of non-english passages. The reader's guide is enhanced with discussion groups and links to online information sources, photos, videos, and other assorted bric a brac allowing you to dive as deep as you like into the world of Ulysses. If you've always wanted to read ULYSSES, but have been intimidated by its size and density, this is a great way in and is a great new way in its own right to experience literature.
Ulysses itself is on the banned and challenged list because of sexual content and language (The File Room and The Free Expression Policy Project have the details and trial results). Ulysses was a book whose trial began to change criteria for obscenity.
Ulysses "Seen," the comic novel was not made available until Apple's demand for cuts was met. All cartoon nudity had to be removed because of Apple's strict guidelines, something Rob Berry and Josh Levitas, the creators of the web comic had not counted on. They had expected to cover areas with "fig leaves" or pixelate certain areas but Apple's policy did not allow for that, so the images were cropped for the iPad.

The Banned Book Challenge continues until the end of June.
