here's the deal. I usually don't reformat my MBP too often but when I do, iTunes really gets on my nerves. I like so many people have an iPhone and of course I have my address book, custom ringtones, videos and music loaded on it through iTunes. the problem is that everytime I reformat my MBP, iTunes flips out and tells me if I hook up my iPhone and try to sync it that it will erase all the content on my iPhone. I thought that was the whole point in logging in my Apple ID and authorizing my computer so iTunes doesn't think I'm trying to share music or whatnot. so my question is, how can I reformat (when need be) w/o having iTunes erase the content on my iPhone? I've tried to back up my iTunes content on DVD but iTunes still does what it does. I hope the Macforums pros can throw me a suggestion or two.
