You may have figured this out already, but I just came across your post and thought I would weigh. You’re most likely looking for a single entry in your wp_options table that contains an array of the WPTouch settings. In my installation, the option name is bnc_iphone_pages. It’s just a long string of field names and values, so obviously be very super careful making any changes to this because one misplaced character, and your plugin is likely to break.
