What is jailbreaking an iPhone and how?
Jailbreaking is not a virus. And it is not illegal either. Definition: "Jailbreaking: The process of bypassing restrictions on iPhones and iPads to install other apps and tweaks not approved by Apple. "

IT IS NOT ILLEGAL! Apple even said so. Just make sure you use a trusted jailbreak software, like redsn0w or greenp0ison.
