I am trying to decide whether I should upgrade to 2.1 or not. The thing is, I don't want to risk losing all the data I already have stored in the my jailbroken 1.0. So will upgrading to the legit 2.1 version require that I have all my data (notes, contacts, calendar...) wiped out in the process too?
Thanks for letting me know.
