Hello all,
I want to jailbrake my Iphone I am on iOS 6.1.3. iPhone 4S. And I have phone this website that you can jailbrake for iOS 6.1.3. But have to pay 24.99. Here's the link: http://www.unlock-jailbreak.net/index.html

Is that site worth it? Cuz I will pay for it if can jailbrake it on iOS 6.1.3!
Another question, what is unlocking do? Does it screw up your warrenty or contract with Verizon? I have never unlocked iphone before.
If anyone can let me know about this. Be much appciated!
