How to set up iphone 4s with out itunes?

Ok i'm getting an iphone 4s soon i don't have an itunes account so i'm wondering how can i set it up without itunes. And don't bash me because i don't have the newer iphone i want what i want and honestly the newer iphones are ugly! All that matters its an iphone! So no rude and ignorant comments on why i'm not getting the newer one because unless your paying for it why do you care? Any who just answer my question.
