husband and wife, 2 iphones -- one address book/calendar?

Hi there,

Was looking for some suggestions. My wife and I just got new iPhone 3Gs. I have a MobileMe account and she does not. I have a MacBook that I use exclusively, but we have an iMac that we share.

I love the MobileMe concept as it will sync my mail, contacts, calendars etc. through my iPhone, MacBook and iMac. Great.

Issue is how to make it work for my wife. She has a Gmail account which she can set up on the iPhone. She wants contacts from the Address Book on the iMac and she wants calendars from iCal on the iMac.

Can she share the same contacts and calendars? We only have one user account on the iMac. If I make a change, it should push to my iPhone, MacBook and iMac. If she makes a change to a contact or calendar, does she then have to sync with the iMac to have it change on the iMac? In theory, if she changes a contact, syncs with iMac, then Address Book in iMac is updated. Then does MobileMe detect that change and sync it with my iPhone and MacBook automatically?

Is there a better way? I am open to getting her a MobileMe account but if we share Contacts and Calendars doesn't seem to make sense since you can only have one MobileMe account set up per Mac OS user account/login. Or can you? If I sign up for a family account, will that solve all of these issues?

Thanks for any insight into how we could best work this out.

Also when my wife tries to sync with iTunes (on the iMac), she can't sync calendars/contacts because it says Syncing is not enabled. She goes into iSync (on the iMac) and Preferences to check the "Enable syncing on this computer" and it says can't connect to sync server.

Any ideas?

Thanks.
