Facebook has the best #1 iPhone application in the iTunes store, and with the arrival of Facebook 3.0, I am sure it will maintain its top position—or even break its own record.

The Facebook 3.0 iTunes App comes with a host of new features, enhancements, and fixes. It includes viewing upcoming friends’ birthdays, the ability to see upcoming events and RSVP to them, write notes, read friends’ notes, and a lot of other cool features.

And there’s something for everybody in this latest app. For photo and video fans, the new version allows them to upload videos and photos to Facebook directly from the iPhone. It also allows creating and managing albums, photo tagging, and updating your profile picture. You can now zoom-in on photos, see news feeds as the Facebook website, and visit links in a built-in browser as well.

As a die-hard iPhone user, I love the new Facebook iPhone version 3.0 app, and I can’t wait to see what the future will bring.
