So I have an iPhone 3GS and haven't updated it lately. I already jailbroke my iTouch 3G via blackra1n, and decided to jailbreak the iPhone too. It is running 3.0.1. I have 2 questions: 1. Can I update to 3.1.2? I only want to this if 3.1.2 is untethered. 2. If not, how should I jailbreak it? Again, iPhone 3GS 3.0.1 Thanks in advance!
