Motorola V600

OK, well thanks to everyone who has posted the settings for Cingular, but I guess I am still confused as to where/how you input them?? Do the different software versions have different settings, because it seems sometimes I have the same spot for the settings, sometimes I dont. I guess what I am asking is for some help for a guy that has never done this before. And after you get the settings all in, do you have to activate them? set them as default? Any help is greatly appreciated!!
