I am still new to all of this so your help is appreciated!!! I used winpwn to unlock and jailbreak my iPhone 4gb running v 2.0. When the new release comes out (hopefully not long after the mac version tomorrow), how do I upgrade my with the new version? Will I have to start from scratch and lose everything I did as well as the app store apps I downloaded or is there an easy way to do it? Thank you!
