iPhone Reverse Engineering

Now before i get any comments like i shouldn't be decompiling code and its illegal to resell someone else's code as my own, i would like to point out that i wont be doing that. 
I'm learning Objective C, but i learn best by example, if i can get into someone else's application, and see how they set up certian things, i can learn better that way.

that said, does anyone know how to decompile an iphone app down the code?

doesn't know how decompiling works
