I'm not sure I know enough about the iPhone to feel confident enough to jailbreak it and feel secure in what I have done...yet. I ran all the leaked/hybrid/you name it OS on my BB, but I'm still too new to the Apple world right now.
Its very simple, and if you find its not for you, going back is even simpler. If you want some help with it i'd be happy to offer a helping word of wisdom or two?
