Downloaded and updated iPhone. Have different content on iphone and ipad. I would like to update the iPad iOS, however have way more content on it. As well, I am concerned that the non iTunes items like music and photos will be deleted permanently - they are not on iTunes currently. Have an original iPad, iPhone 4 and would like to be able to (via cloud?) choose what goes on the pad the phone, etc. while preserving content on the pad which has the most content. Thoughts? Please?
