How to change a default application in Ice Cream Sandwich?

I used the ADWLauncher EX by default while having Gingerbread 2.3.6.

Today I have manually updated my Nexus S to Ice Cream Sandwich 4.0.3, and I wanted to give the new default launcher a shot, but I cannot find anymore where to select / forget the default application for an action.

I've turned the settings of my phone inside out, googled and crawled the forums, but without success.
If anybody can tell me how to change a default application in ICS, I'd be grateful!

Yeah, I never thought I'd want to see that Complete action using... window again! :D

Answer

Go to Settings, Applications. Find the app that has the default set. Scroll down to the bottom of that view and click the "Clear Defaults" button.
