You already know the first part of this story. James Joyce's magnum opus Ulysses was banned in the US from its publication in 1921 until 1933.
Now it seems that history is repeating itself. Apple has banned a graphic novel adaptation called Ulysses Seen from its gadgets. It seems one of the comic's panels shows some fleeting male nudity, and thus the whole work has been deemed pornographic.
Thanks to The Big Money for the catch.--David E
