All About Iphone

You can sync the iPhone with iCal (Mac) and Outlook(Windows) calendars. To set this up, attach your iPhone to your computer, select it in iTunes’ Source list, and then click on the Info tab. You can sync all the calendars in your chosen calendar program, or choose to sync only a select group. To save space on the iPhone, you can also limit how many old events sync to the device.Although you can view the contents of multiple calendars on your iPhone, you can’t create events and assign them to those calendars. Instead, you’ll need to use the Info tab in iTunes to choose a single calendar that will receive all the events you create on your iPhone.If you’re a Mac user who uses Microsoft Entourage as your calendaring program or address book, don’t despair: there is a way to use Entourage with the iPhone. You’ll need to be using Office 11.3.5 or later, which may mean downloading an update from Microsoft.

In Entourage, choose Entourage: Preferences, and then click on Sync Services. Check the boxes for Address Book and iCal syncing. You’ll be prompted to choose whether to replace Sync Services items with Entourage items, replace Entourage items with Sync Services items, or merge Entourage items with Sync Services items.
Your choice will depend on what data you’ve stored in Address Book, iCal, and Entourage.Unless you specifically want to wipe out the contents of the Mac’s Address Book and iCal, which might not be wise, especially since Address Book data is used for items such as Buddy names in iChat—the safest approach is to choose Merge. Once you’ve set up Entourage to sync with iCal, you should be able to sync those calendars with your iPhone as well.
