Im just about to download the 3.0 update for my touch. I have thought about jailbreaking my touch for quite a while, but have always felt it was too risky to do on such a fragile, expensive device. Here are my questions: What does jailbreaking do, and how risky can it be? What is the best way to go about jailbreaking it? (Best Videos, websites to follow) How easy is it and what benefits do you receive from jailbreaking it? After you jailbreak it, is it possible to restore your touch, therefore unvoiding your warranty and making it as if it was never jailnbroken?
