I should be getting my imac today and am currently using a PC. What am i supposed to do about my iphone? My library, apps, podcasts etc are in itunes. I don't mind losing my library, im transfering my music over to the new mac so i can re populate the music. Will my apps and stuff transfer over when i plug my phone into the mac? I've also heard about deauthorizing my account. What is this and do i need to do it? Any advice to help the transfer would be appreciated.
