How to jailbreak iPhone 4 version 5.1.1 without connecting to a computer

How can I jailbreak my iPhone 4 version 5.1.1 without connecting to a computer?

You can't. Sorry:[

Yeah sorry to say that jailbreaking with out connecting to a computer is impossible, except for very old firmwares. If you end up being able to jailbreak through a computer, I would recommend you go to iphonefivejailbreak.com and do it. If you don't know how to.

No you need a pc to jailbreak 5.1.1.
