There are a number of ways to backup Address Book (Time Machine, Export Address Book Archive..., or vCard), so restore them whichever way you backed them up.
Once your contacts are back in Address Book, chose Reset Device in iSync to ensure the contacts go from Mac to phone.iMac 20", MacBook, Time Capsule, Airport Express, AppleTV 2, Mac OS X (10.6.6 + 10.7) - iPhone 3GS 32GB, iPad WiFi 32GB
Currently Being ModeratedMar 12, 2011 12:05 PM (in response to _Stephanie_)If you don't have any backups, there is nothing to retrieve your contacts from I'm afraid. Time Machine is designed to be left on all the time, so you always have a regular, up-to-date backup.iMac 20", MacBook, Time Capsule, Airport Express, AppleTV 2, Mac OS X (10.6.6 + 10.7) - iPhone 3GS 32GB, iPad WiFi 32GB

from a suitable backup, making sure that Address Book was not running during the restore. I quit and restarted the iMac, but Address Book still shows 0 cards.
Any ideas on what I did wrong, or what I can do to get my contacts back?2GHz iMac, 2.4GHz MacBook, iPad2, Mac OS X (10.6.7)
Currently Being ModeratedApr 12, 2011 1:57 AM (in response to urlgurl)I'd suggest asking in the Address Book or iPad forums, as iSync is not involved in syncing contacts to an iPad.

I just had the exact same problem. I went into iCloud on my iPhone, switched off contacts, selected "Keep contacts on iPhone". Then I went to iTunes, connected my iPhone to my mac and clicked on the Info tab. Just tick the box that says "Sync address book contacts" a=then hit apply at the bottom of the screen.
And there are some tutorials about iPhone Contact Transfer, maybe it can help keep you contact safe.
Hope this works for you.

Thanks so much for posting that information - I had been trying for days to get my contacts from my iPhone and iMac to somehow upload to 'the cloud' with no luck - calendar seemed to upload to the iCloud okay and has been syncing between devices, but contacts just were stuck where they were. Anyway followed the tip about exporting the contact v.card file thingy, and then putting it back (on the iMac) and now my contacts are up in the magical cloud finally, and it syncs with the iPhone... At last!
So thanks again - it was really helpful for me (and relieved to hear that you got your info back after that drama too!)

2.Select "Restore" from Summary tab.
3.Decline the option to make a backup by selecting "Don't Back Up."
4.Select "Restore" to confirm you wish to restore your iPhone. Your last backup, including restore lost contacts of your iPhone. Your iPhone will re-start and display the Apple logo.
5.Follow the steps offered by the iOS Setup Assistance for iOS 6 and later to clear the "Connect to iTunes" message. For earlier versions, leave your iPhone connected via your USB or Wi-Fi until the message "iPhone is activated" appears.
