Resolution independence???

Hey everyone.
I am almost finished with my first two games, which have both be made 320 by 480
If I want these to look great on the IPhone 4, what should I do?
I looked at the info provided by Gamesalad, but got kind of confused.
I was hoping that someone could help me out.
Thanks,
