There is actually a guide posted in Android Development by Imnuts... It tells you exactly how to dump everything (and make a odin image, which would be nice to share... Ours right now ain't too good :P)
However, if your talking about dumping the radio, no can do.. We need a radio leak, which Adrynalyne was working on getting a while ago... He lost his source though, so no luck since....
