The third major edition of Facebook for iPhone has just crept into the iTunes App Store. It's a huge update, with numerous advanced features that make Facebook more interactive than before and which bring the app as close to the desktop experience as it's ever been.

Facebook for iPhone opens on your news feed as usual, but the upper left corner now sports a tiny grid icon that serves as the main organizing feature for this new build. Click it to see a screen equipped with a search bar on top, a notification alert area on the bottom, and a grid of nine activities you can perform in the middle. These include the news feed, your profile details, your message in-box, Facebook chat, friend requests, events, photo albums, and notes.

Those who use Facebook on the iPhone frequently will notice that quite a few of these actions are brand new, like viewing events and submitting an RSVP from your phone. You'll also be able to view friends' birthdays and upload photos to any album. Anyone sporting an iPhone 3GS gets the added bonus of uploading video.
