Please read this comparison so you are clear on the differences between free hosted WordPress.com blogs and WordPress.org install for self hosting. http://support.wordpress.com/com-vs-org/
The Spun theme is a WordPress.org theme and cannot be used on free hosted WordPress.com blogs. if you wish to request that the theme be adapted to run on our software and added to our Themes Showcase http://support.wordpress.com/com-vs-org/ then see here please.
2. Post a suggestion for a new theme
Please give us the theme name, a link to view the theme, and—most importantly—why you like it and would love to have it on WordPress.com.
Please search the forum first for a suggestion on the same theme. If it exists, add your vote to the same topic and add a note about why you like the theme. http://en.forums.wordpress.com/topic/how-to-use-the-themes-forum?replies=1

NOTE: There is no FTP access to free hosted WordPress.com blogs and we bloggers cannot install any plugins or upload any third party themes.
The only themes you can use on a free hosted WordPress.com blog are those found here > Appearance > Themes and showcased here > http://wordpress.com/themes
There is no upgrade you can purchase that changes anything at all stated here http://support.wordpress.com/com-vs-org/
