You can now use the Share button on News Feed stories from your phone whether you’re using the Facebook for Android app, the Facebook for iPhone and iPad app, or the Facebook mobile web site. This gives people a fast way to share stories with friends from their mobile phones, just as they can from their computers.
When you click Share on a news feed story in your Facebook app or on m-site, you can re-post the story on your own Timeline so your friends can see it.
