Today, Facebook introduced its updated universal app that will run on the iPad. With version 4.0, you can now log in without tapping 2x to see an expanded iPhone view.
Not only does landscape mode make it easy to see more, now you can simultaneously view the news feed and chat with friends on line.
Portrait and landscape modes are available.
You can now see and share higher quality photos.
If you can’t get enough of Facebook, now, you will see and have more Facebook real-estate with the iPad version.

I downloaded and installed the iPad version from the App Store. Looks pretty nice.
