Is it possible to jailbreak an IPhone 4s, IOS 6.1.3?

I know that there are tons of people who already asked similar questions but after almost 4 hours of looking for a solution i gave up. I tried snowbreeze and that didn't work because i couldn't find or download the right IPSW.
Is there a way to jailbreak the 4s or was all my searching for nothing?

There's no available jailbreak support for IOS 6.1.3 for iphone 4. I believe this june. IOS 7 will be released and a jailbreak for it is being prepared.

Stop trying, there's no genuine jailbreak for your device on that iOS.
