Syncing 2 I phones with one MAC

Question

I just purchased the new IPhone 3G....I want to sync it with my MAC. My wife also has an IPhone. How do we sync both phones to the same computer and keep our calendars/contact etc, separate?

Answer 1

You won't be able to keep Address Book contacts and calendar events separate with the Address Book and iCal under the same user/login account on your Mac.
She can have her own separate calendar or calendars in iCal and select only those calendars to be synced with her iPhone, but her calendars and your calendars will be available in iCal under the same user/login account.
She can create her own Address Book Group or Groups with the Address Book application and sync only those Groups, but her contact information and your contact information will be in the Address Book under the same user/login account. A contact cannot be placed in an Address Book Group unless the contact is in the primary Address Book "All" Group.
She can transfer select iPhone albums to be transferred to her iPhone, and she can create her own iTunes Playlist or Playlists to be transferred to her iPhone.
If you want to keep contact information and calendar events completely separate, you need to create a user/login account for your wife on your Mac. This will give your wife her own Home folder directory to store her data only. Each user/login account includes a shared folder where files that need to be shared between multiple login accounts can be placed.
She can sync her contact information and calendar events only with the Address Book and iCal under her login account. She can access her email account or accounts only with the Mail.app under her login account.
She can sync iTunes content and transfer photos from iPhoto only under the existing login account of with your login account, and contact information, calendar events, and bookmarks only under her login account.
You can enable Fast User Switching to make the process of switching between multiple user/login accounts a fast and easy process.
