I remember when you could get an RSS feed for a Facebook wall. Years after that when away there was an RSS feed for Page posts, but I think that’s gone now.
Up until a year ago there was some obscure way to see the Pages Feed (all Pages) in Facebook Mobile, but I think that’s gone too.
AFAIK the only way to view a page feed on mobile is to save the URL to the Home Screen. Go to https://www.facebook.com/pages then click on tab feed then save. Safari will sync un/pw via keychain across Safari on devices.
Looks like Facebook only wants Pages to show up in the news feed, and then only for a price.
