I'm concerned with all the data from my old iphone, contacts, text messages, emails, music, recordings of voice memos, paypal, skype, linkedin, wells fargo, and on and on. I have no idea where this data is stored on my mac.
Of course email is easy and music will be synced from my itunes but the rest will not unless i know where it lives on my mac and exactly HOW to get my Itunes to sync it with the new iphone. There is no clear or prescribed way to do what you are saying and I cannot risk losing this data.
What danger do you believe there is in telling iTunes to restore my old iphone data? Do you really think the jailbroken apps and data will corrupt the phone?
Also, if I tell iTunes to consider my 4s as a new phone, don't I run the danger of losing all the old data? Itunes may just wipe it out thinking it is no longer needed!! I cannot risk this. I need to preserve my old data.
