Jailbreak Instructions for all

To see what version of the iOS (operating system) you are running, go to Settings >> General >> About.

Choose the iPhone Jailbreak guide that is right for you. Read everything extremely carefully, including comments, before attempting to Jailbreak. I have not personally attempted all of these, so jailbreak AT YOUR OWN RISK.
