Also Kies is only being supoorted for the int'l versions of the Galaxy S or SII (GT-i9100 the one I have) or the GT-i9000M/T (the first gen. Of Galaxy S), but not the carrier version of Samsung smarphones such as the infuse 4G unless I'm wrong. This is very pitiful because HTC Sync software allows just about any HTC device running android to sync their PIM, music and pictures.
I am succesfully able to sync my GSII with kies using Outlook, b/c I have an int'l Galaxy SII fortunately. I use windows 7 operating system also. I'm able to sync all of my contacts (168 entries), notes (67 entries), calendar entries (over 135 entries), my music and pictures. For some weird reason Kies will not sync my itune playlists, so I resorted to iSync software for syncing all of my music library and playlists. As far as contacts, calendar entries and notes syncing with Outlook, kies works perfectly (I'm very happy)
I hope this helps.
