Is jailbreaking an iPhone safe?

I'm getting an iPhone 4S very soon, and I'm thinking about jailbreaking it. I don't want to risk breaking it, because I won't be able to get another if something goes wrong… So is jailbreaking safe? I'm thinking about using RedSn0w, GreenPois0n, or BlackRa1n if I do decide to jailbreak my iPhone…

Compared to base jumping it is

Well I used redsn0w and it was fine, remember, jailbreaking is never safe, something can always go wrong, but its less likely to if you know what you're doing. Youtube jailbreaking iphones/ipods- you do it the same way- and there will be bunches of videos telling you how. When you use redsn0w remember to add cydia, so much better with cydia.

Yes i have done it on on greenp0ison you can't turn of you device

Yes it would be safe to jailbreak.

Jailbreaking has come a very long way and the only thing that can possibly go wrong is you having to do a factory reset to it if you mess it up.
