Sharing on Facebook??

[luckycheeks]

I have a new iPhone 4s. Is there a way to share a post on fb? For example, I see a post with a pic and caption in my feed and I would like to repost/share it on my wall.

The only way I can share is to open Safari, go to the full FB web site and share from there. This is the only way I know how.
