How to jailbreak an iPhone 3GS?

I read up on it, and decided I want to jailbreak my phone. It's warranty is up now, and I'm getting an iPhone 4S soon anyway. It has the newest iOS. Can someone explain how to jailbreak my phone, and maybe recommend some good websites for it? I want it to not cost money, and preferably not need a computer. I'm at my cousins and don't have my laptop, so I want to jailbreak my phone right out of Safari, if that's possible while it still being free. And please, when you explain how to do all this, try to make it easy to understand. My friend was explaining it and I was like What? Anyways, thanks!

Plug your phone into the cOmputer and download.
DON't DO IT! FACTUAL RESEARCH BY APPLE SAYS THAT AN APPLE IPHONE CAN ONLY LOSE ITS BATTERY LIFE So MANY TIMES. BY JAILBREAKING IT LOWERS THOSE NUMBERS. Your PHONE WON'T LAST LONG. APPLES POLICY STATES THAT your WARRENTY IS COMPLETELY DISABLED IF YOU JAILBREAK (even if it's a physical break on the phone). APPLE MAKES SURE THAT your PHONE COMPANY WILL DISABLE your WARRENTY. IT ALSO SLOWS DOWN YOUR IPHONE. TRUST ME I KNOW All OF THIS BECAUSE IT HAS HAPPENED TO ME BEFORE. DON'T DO IT!

On youtube I'm sure ull find the howto

Use jailbreakme and check the guide on youtube.
