Does anyone know if there are any good PGN viewers available for mobile phones (Sony Ericsson if that matters)? I haven't found anything for this specific purpose but the closest thing was a chess client that allowed you to analyze games in pgn format (Chess Genius for Nokia phones)

Check out www.chessok.com

They have a bunch of software for portable devices as last weeks offer. I think the offer expires today (Sunday)
