We knew it was coming in all of its glory. With additions such as events, creating photo albums, photo zoom, and a new home screen, how could we not be excited for the Facebook for iPhone 3.0 update? Well, the wait is over: Facebook 3.0 for the iPhone has arrived.

The new update completely upgrades the Facebook iPhone app, still the #1 most popular application in the iTunes store. And let’s be clear: this upgrade was absolutely essential. While Facebook 2.5 allowed you to browse your friends, update your status, check your notifications, and use Facebook Chat, that’s really all it could do.

So what’s new in the app? Joe Hewitt, the developer of the Facebook iPhone App, actually has a list of new features and improvements posted last week. Here’s what’s in store for you when you open up Facebook 3.0:

– See your upcoming Events and RSVP
– See your friends’ birthdays
– See Pages and post updates and photos to Pages you administer
– Write Notes and read your friends’ Notes
– Upload videos from an iPhone 3GS
– Upload photos to any album
– Complete photo management (create albums, delete albums, delete photos, delete photo tags)
– Change your Profile Picture
– Zoom into photos
– Like posts and photos
– See the same News Feed as the Facebook website
– Visit links in a built-in web browser
– See all of your friends’ friends and Pages
– See mutual friends
– Easily search for people and Pages
– Make friend requests
– Become a fan of Pages
– Quickly call or text your friends
– Create shortcuts to your favorite friends and Pages
– Friends sorted by first or last name according to your settings
– Chat friends sorted alphabetically

Pretty amazing list, indeed. This should cement Facebook’s place as the top social app for the iPhone for awhile.
