Wife gets 4S today. She has iCloud account (nothing in it yet). She uses Gmail now and wants to continue using that for email. We exported her Google contacts to a Vcard file, it's on the desktop on the Mac (running Lion). I open her iCloud account on the iMac, and there's a box with things to check (Contacts, documents, etc). My question is: how to I import that Vcard file with her contacts to iCloud so it will synch with her new phone? I saw where I was supposed to drag it into the Address book but I don't see how to open that book on my PC. Hers is the only iCloud account we have (I don't need one yet). I don't mind using iTunes either if that's easier. Thanks in advance for your help.
