[SOLVED] different settings files in database?

hello,

I'm not sure if I'm in the right part of the forum, but it seems the most appropriate.

since Atahualpa does not have a mobile setting, I decided to use a plugin that redirects mobile users to a different theme within my wordpress setup. for this theme I duplicated the Atahualpa theme that I had just configured, called it Atamobile, and started editing the new theme to make it more functional on mobile devices. but when switching back to the 'normal' Ata theme, I saw that it had taken all my new edits to the old theme as well!!!!

I'm guessing that the theme options are somewhere stored in the database instead of the theme folders, so this is my question: how can I set up a different theme options file for my mobile theme?
is there a file I can edit so it would use another database entry for each setup of the theme?

thanks,
Eric.
