Jailbreak my iphone 4 iOS 6.1.3 no computer?

I tried hundreds of websites literally and I still don't know how. I tried jailbreakme.com but it said it doesn't work yet with iOS 6.1.3. Please Help ME! I really appreciate any kind of help. I need feedback As soon as possible!

You can't jailbreak that version i think if you can check out evasion and redsnow

WELL if you jailbreak your phone you do realize they can shut if off

For jail-breaking a iPhone 4 or iPhone 4s You might use this software

Sorry, you need a computer for all jailbreaks after iOS 4:/ just download iOS 6.0 to your computer then download redsn0w. In red snow click extras the select Ipsw. Select the iOS 6.0 you downloaded and use that. Then click jailbreak then make sure it says install cydia. After that wait for it to inject the jailbreak stuff then press extras, just boot. Once you can unlock and use your device then you can unplug it from the computer. Hope this helps!
