I’m using three20 for my dashboard.
(ttlauncher)
Now when I select a icon to open a screen
How do I make the screen open like Facebook? (small to big)
And close to return to the dashboard like Facebook? (big to small)
Do I need to modify the ui screens to use three20 aswell? Or the effect is standard iOS effects?
These are custom animations developed by the team who worked on the App.
If you download the Facebook iOS SDK you should be able to have a glimpse at how it’s done by looking through the source code and using it as a reference.

Of particular interest to you is the FBDialog class (which is a UIView subclass).
