Hot to Sync Facebook Events to iCal

You can sync your Facebook events to iCal (Mac's default Calendar).
1. Login to Facebook and go to "All Events"
2. Scroll to the bottom of the page and click "Export Events".
3. Click that URL , then your browser may prompts you that it will launch your default calendar app.
4. Once your default calendar launch, you can click "subscribe".

Then it works.

P.S.
You can't update the Facebook events on your calendar app in this method. It is an one way sync.
This is the same method to publish those events to your iPhone calendar from Facebook.

iPhone Apps -- TweetDeck For iPhone

It is a application in your mobile for you to keep staying in touch with what is happening now on Twitter from your iPhone. Besides, it can also support Facebook so that you can keep knowing your friends status in Facebook from one application.

Before that I am using "Echofon" for Twitter updates but now I changed to "TweetDeck for iPhone". Because the interface is cool and you can update your status of Facebook too ! And it is free !!!!

Here is the web site of TweetDeck.

In this web site, there is a desktop software called "TweekDeck" for you to manage Twitter, Facebook, MySpace and LinkedIn in one application. It looks good and I will try it !
