How to jailbreak my iPhone 4s ios 6.1.3

How do i jailbreak my iPhone 4s ios 6.1.3?!

There isn't a real jailbreak for 6.1.3 and higher. This is because 6.1.3 and 6.1.4 are minor upgrades, and creating a jailbreak for it would just waste exploits.

Think of exploits as a loophole to unlock something. Like unlocking a car from the inside because the window was down. Eventually, the person will figure it out and "patch" or fix the loophole by closing the window. Soon, it will be hard to figure out other exploits, as the discovered ones have already been patched.

You can't jailbreak iOS 6.1.3 and there probably won't ever be a jailbreak for iOS 6.1.3 (or higher). Developers would be able to create a jailbreak, but since the update from 6.1.2 to 6.1.3 (& 6.1.4) are so small, they do not want to waste their exploits. I don't know exactly how it all works, but the bottom line is this: if they jailbreak 6.1.3, it will only make it harder to jailbreak future versions of iOS.
