This morning at SXSW in Austin, Facebook Senior Platform Manager Dave Morin announced the official launch of Facebook Connect for iPhone. With Facebook Connect, iPhone users will be able to easily connect with Facebook friends through iPhone apps & games.

Participating in the launch announcement today were some of the biggest social game developers on both the Facebook Platform and iPhone:

• SGN announced the launch of Agency Wars, a new game with Facebook Connect support, as well as an iBowl update with Connect support
• Playfish announced the launch of Who Has the Biggest Brain on the iPhone, with Facebook Connect support, with 2 more titles coming soon – Geo Challenge and Word Challenge
• Zynga announced official Facebook Connect support in Live Poker
• Tapulous announced Facebook Connect support for Tap Tap Revenge
• Flixster announced Facebook Connect support for the Flixster movies app
• As did Urban Spoon, Binary Game, Whrrl, and more

In other words, it was a big launch event. While a couple of iPhone apps from SGN and Zynga have authenticated through Facebook Connect via the web in the past, this is the first native iPhone app support ever. Facebook Connect for the iPhone has the potential to transform the way iPhone games are designed and shared, and could provide a new and more authentic way for apps to spread and climb the iPhone app charts.

Here’s how the first games with Facebook Connect for iPhone live look:

Who Has the Biggest Brain for iPhone (Playfish)

Who Has the Biggest Brain for iPhone, users can connect through their Facebook account and continue playing Playfish’s classic game on their iPhone anywhere there’s an internet connection.

Agency Wars (SGN)

SGN’s new Agency Wars lets players see when their friends are live online and interact with them in real time.

Binary Game

We’ll be staying on top of the development of iPhone games built with Facebook Connect closely in the coming weeks and months!
