When you go to a Facebook wall from a PC, there are tabs in the left margin with more info. Especially on biz pages. My favorite restaurant has Friday specials that they post to a "Friday Specials" tab. The specials say to print or show on your phone to get the special. I have contests and other events in tabs on my biz pages.
I can not figure out (nor could the restaurant) how to get to the tab listing in the android app. I can not find it tabs in the mobile fb site either. How do you get to tabs from an android phone? Does the i*hone app display tabs?
