Integration of Facebook Group Wall in iPhone app

Question

Hi all,

Is it possible to integrate a wall of a specific Facebook group into an iPhone application. Is it possible to do using Facebook connect? or any other libraries?

1. The task is to display the wall of a group. Can we bypass sign up and display the activity on the wall on the tab?

2. Would it be possible for a registered FB user to make posts from our iPhone app?

Thank you,

Slava
