How to jailbreak my iphone 4 ios 6.0?

Everytime i try and do it, it'll say 'EXPLOIT FAILED" I don't know what that means but i'm getting really frusterated trying to do this.
also, i watched a video on youtube, and it said download putty, i did that and a screen pops up and i have no idea what to do when i get there. All the vids on youtube seem to leave that part out.

someone help me with this.please!

Added (1). I'm not sure what thats supposed to mean.also, how do i get my IP address?

Fking apple minions… Smh

edit: its not surprising that you can't figure out how to do it; after all, you did buy an apple product.

Jailbreaking is bad for your phone. Seriously.
