Which application on your Mac are you syncing contact information with - the Address Book, or with Entourage's address book?
Are the contacts available in whichever application on your Mac that you sync your contacts with?
If not, do you maintain a backup of this data along with all the other important data stored on your Mac?
If the contacts are still in Address Book on your computer, but just not on the phone, you can tell iTunes to force replace the contacts on your phone with those from your computer. You can do this by going into the Info tab when your iPhone is connected, and checking the Contacts box under the Advanced section at the bottom of the page.
You may also want to backup your Address Book information as well. It's a good idea to make periodic backups of your contact and calendar information in case information accidentally gets deleted or changed. You can find out how to backup your Address Book data here:
