You have been waiting so long folks for the actual iPhone 3.1 OS jailbreak to arrive and the iPhone Dev Team has delivered. Your iPhone 3GS is ready to be freed. All you need to do is get the Pwnage Tool 3.1.3 but only if the phone was jailbroken when running iPhone OS 3.0 or 3.0.1. That shouldn’t be a problem, should it?

Of course, we don’t recommend in any way that you jailbreak and/or unlock your iPhone, or any other phone for that matter. It’s solely up to you to take such decision, and before you do, take a personal moment and consider what could happen if you messed up your phone. I bet the manufacturer and your carrier will not be happy to hear about your hacking activities. Those of you that still want to jailbreak, follow the link below at your own expense!
