wtf are you talking about, kittyra1n is a jailbreaking website, not an actual jailbreak tool
which it clearly states, it does work, I jailbroke my verizon iPhone phone with kittyra1ns tutorial
DO RESEARCH BEFORE YOU SAY SOMETHING IS UNTRUSTED
First of all pay attention on how you expressing your self on the forum.
Second, I was talking about downgrading iOS, not jailbreaking iOS.
