Got this off a blog. Seems like they added a few new features to it. The only bug I have found is that the notifications don't seem to work for me. As far as getting them on the notification bar or the LED to blink. There is a notification button in the app that will show you the new notifications with a link that will still take you to the comment but in a browser and to the mobile site just like the old version does. It's a little better then the old stock FB app but I really wish the notifications worked like the old stock FB app where they show up on the notification bar.
Uninstall old stock FB app before installing this one.
