Importing Contacts from your computer

If you're Macintosh user, there are four contact manager applications that let you sync directly from your computer to your iPhone, and they are: (1) your mac's Address Book application. (2) Microsoft Entourage. (3) Yahoo! Address book, or (4) Google contacts.If your contacts are in any one of those four, when you plug your iPhone into your computer, it launches iTunes and syncs the contacts on your computer with your iPhone (if you have this preference set). Or, you can click on the info preferences tab in the main iTunes window, and choose which contacts to sync, If you're working on a corporate microsoft Exchange Server, see your IT department for the proper setting. If you have a MobileMe(.mac) account, you can set your iPhone to sync from within your computer's System Preferences.

if you're a Windows PC user, it works pretty much the same way, but the four contact managers it supports direct importing from are: (1) Yahoo! Address Book, (2) Windows Contacts (3) Microsoft Outlook, and (4) Google Contacts. Of course, if you're corporate user on a Microsoft Exchange server, you can get your contacts over the air, as well. Again, see your IT department for the settings. If you have a MobileMe account, you can change your setting from within your computer's MobileMe preferences, found in your Control Panel in the network preferences.
