Jail breaking iPhone

[Avaj]

I think I'm finally going to jailbreak my iPhone 3GS (yes the old version of the iPhone) anyways....have a few questions as I tried to research this & still little bit confused.

Can I jailbreak it for free or it is best to pay to have it done?
Do I have to unlock it first then jailbreak?
Do I have to have a computer to jailbreak or can I do it straight from my phone or ipad?

Thanks anymore useful information will be greatly appreciated.

Yes you can jailbreak it for free
No unlocking comes either with the jailbreak or after it
You can either use a computer or do it straight from the phone.

Just make the jump to Android and let your inner nerd out

Do you know of a good site to do so?

What does jailbreaking an iphone mean? I still don't have a data plan on my cell phone, but I guess I could get one. I do have an iphone. I'm just stubborn about using it.
