How to jailbreak iPhone 4s ios7.1?

Hi, I've jailbroken my iphone before w/ my computer but unfortunately I do not have my computer anymore, so now I need a way to jailbreak my iphone w/out a computer. Is there any possible way to do a legit untethered jailbreak w/out a computer? 10
Points for best answer and a link would be great thank you.

I worked for apple all you will do is brick it then think apple will replace it but no they won't. I don't recommend it
