I want to jail break my Ipod Touch but I have some questions? 1: What is so good about jail breaking a ipod touch? 2:Will Jail breaking void my warrranty? 3: If it does void my warranty then is their any way to restore it so that apple will cover it? 4: Is there any way to completely restore it to pre jail break settings? 5: Will my applications from before the jailbreak still be usable?
