Single Section & Category Display

Is there a way to have only a single section and category displayed when viewed in mobile? For example, I have a section set up called mobile, with a category also named mobile with articles in the category. When a user access the site via a mobile phone, with this component installed, is there a way to have just those articles displayed under that section and category?

Thanks for the replies!

Two-step solution:
1. Make a mobile menu with items corresponding to mobile versions and choose this menu in mod_mj_pda_menu/mod_mj_iphone_menu/??? module.
2. Get a link of a first item in mobile menu and set it as a homepage in MobileJoomla settings of corresponding mobile markup.

Hi, this is ok.
Just I don't know why menu item don't respect the settings, for example I don't want to see author and date into blogsetion view, so I set to hide into Component Parameters for that menu item, but I see them again in frontpage. Is this a bug? because for the second menu item it work and it has exacly same settings.
