how to change icons and screens in phonegap?

All I can find is documents and the like that are like:
Put this in your config file, make sure the icon.png is in your root
folder.. ok. I have tried this all I don't even know how many $*U%)#ing
times and how many different ways.. either no changed get applied, and the
default phonegap logos show up.. or the app crashes:
Terminating app due to uncaught exception

Anyone got any idea's what I might be doing wrong? cause I believe I am
following the docs pretty well, and this apparently seems to be a common
problem for people. But other than people saying put the above in your
config and magic will happen, no one ever resolves the issues, or confirms
it?
