How to jailbreak your iphone 4s?

I've got the iphone 4s and i kind of want to jail break it. I'm going to ask my uncle if he knows someone who can do it since he always has the hookups like when he knew a guy to fix my broken xbox 360. But before i ask i wanted to see if i can do it myself. I really don't know much about it though. How do you do it. And i heard that its kind of easy to mess up and brick your iphone but i also heard that with the 4s you can restart your iphone or something and try again. Is this true? Also can i get widgets on a jail broken iphone

You can jailbreak it with redsnow.
