Applying function to nested lists

Hello,

I'm trying to get Mathematica to do the following:

Suppose
x = {{1,2,3},{{4,5,6},7,8},9}
f = some function

How can I get f applied to each element of x but with the list structure 
intact?  I.e. I want something that generates:

{{f[1],f[2],f[3]},{{f[4],f[5],f[6]},f[7],f[8]},f[9]}

Thank you!
-Kerry Kim
