Best Way To Jailbreak Iphone? - 1

I have an iPhone 4s & it is running ios7.0.3. I'm thinking of jailbreaking it but I don't know how. Can someone please explain how & if there's anything bad about jailbreaking?

There's no jailbreak for 7.0.3

Unfortunately there's no jailbreak for 7 yet. It will take time to release it. Jailbreak won't harm your phone its just tweak to get access to use paid crack apps n customizable. Jailbreak lovers should never update ios unless its jailbreak is released.
