Jalbreake iphone iphone 4s 7.0.2?

Hi is there any way to jalibreak iphone 4s version (7.0.2)?

Yes, download the jailbreak tool called evasi0n from their official website. Then plug in your phone to your computer. Launch evasi0n and make sure it detects your iPhone, then click jailbreak.

I would also recommend that you change your root password in order to prevent viruses from taking over your phone.

Simply use evasi0n to do it. Here is a detailed tutorial http://www.syncios.com/blog/how-to-jailbreak-ios-7-using-evasi0n7-on-ipad-iphone-and-ipod-touch-5g/
