What's a free and safe jailbreak for iOS 6?

I have a iPhone 4 iOS 6 and I want to jailbreak it. I need it free and safe. I have a few questions to ask…

1) I heard that RedSn0w is good, but it costs a lot. Is there any suggestion for a safe and free jailbreaking site?

2) If so, does it come with Cydia?

Thanks if you gave me answers. I might have more questions when I get it.

OMG never ever pay for Redsnow it is always free if you pay for it it meant that you got scammed. By the way you can only do a tethered jailbreak right now with ios6 using redsnow it means every time you reboot your iphone or it ran out of battery you have to jailbreak it again.here is the link with free redsnow and all of the information that you need. Please DO NOT PAY FOR JAILBREAK IT IS ALWAYS FREE.
