I've tried Googling this question, but can't seem to find a definitive solution that allows me to keep my application data and iPhone preferences. I've got an iPhone 3G S which I have tuned right to perfection. All of my apps are organized perfectly on 4 pages and I have tons of app settings and data compiled on the iPhone (save games, application data, preferences, mileage log files from RoadTrip, etc). Now, however, I'll be moving to a MacBook Pro next week. I don't really give a hoot about my playlists or playcounts on my songs, but I would simply like to know if moving from a PC to a Mac on iTunes will wipe out all of application data on my iPhone and make me start from scratch? Syncing the contacts, music, calendar, etc isn't a big deal to me (that should be easy). I just need my application data. Or if it does wipe it out, is there a way for me to save my settings beforehand and restore them on a Mac?
