I am posting this thread for my dad who has an iPhone that he currently uses on a PC. Later this week he will be buying an iMac(thanks to me convincing him). He is wondering what will happen with his address book that he currently syncs from outlook. When I did a clean install of Leopard on my iMac, I plugged in my iPhone and it transferred my address book, safari bookmarks, and iCal events from my iPhone on to my iMac. Will a new iMac take may dad's address book from his phone and sync it into Address Book on the Mac? I have no experience with this, if anyone does and knows how the new iMac will treat the current info on the iPhone, please let me know. Also if anyone else has any other advice in switching from PC to Mac with the iPhone that would be great too. Thanks for any help.
