iPhone requires a Mac with a USB 2.0 port, Mac OS® X v10.4.8 or later and iTunes 7; or a Windows PC with a USB 2.0 port and Windows 2000 (Service Pack 4), Windows XP Home or Professional (Service Pack 2). Internet access is required and a broadband connection is recommended. Apple and Cingular will announce service plans for iPhone before it begins shipping in June.
So why doesn't it work? I am like you and use Windows 2000 with Outlook 2003 and would like to sync my contacts. Otherwise I am going to have to put them in by hand. So I wondered what happened with this and why it's not working with Windows 2000.
