How can i remove unwanted app like Stocks, Maps... etc icon from the springboard?

How can i change the 4 icons on the dock?

1. use poof to hide applications (i'm pretty sure that's what the app is called)
2. assuming you're on 1.1.3 and above, press and hold any icons until they start to wiggle and you can rearrange them
