Facebook for iOS gets updated and brings enhanced sharing, status icons
Another added feature is the enhanced ability to easily change who can see what you have shared. Not only are you limited to just “you” or your “friends” or “public.” This feature provides a bit more granular control to the user in terms of privacy. That is not such a bad thing nowadays.
Finally, you can incorporate icons, or emoticons that are linked to how you are feeling when you post a status update. There are numerous categories too. Right now, the new icons are available only in English.
Now we just need to sit tight and wait for when we will see hashtag support finally make an appearance on the social networking site. Who knows what other goodies they have in store for us.
