How to jailbreak iPhone 4 iOS 6.13 without computer?

Jailbreak me is not working on my phone. I had my I phone 5 jail broke by using evasion on my friends computer, loved it worked perfect. I cracked my screen so now I have to wait to get my new one. I'm now using my old iPhone 4. I jail broke it yesterday usibg same software but it gave my laptop to many virus' and now that's getting fixed. So if anyone could please help me get cydia or jailbreak my phone without use of computer it would be so greatly appreciated!
