Not sure why you posted your iPhone question in the support forum for the Apple routers.......the AirPort Time Capsule, AirPort Extreme and AirPort Express.

You will likely receive a more informed answer if you post your iPhone question in the iPhone support forum. The link is just below.

Using iPhone

If you have backed up your iPhone to your local computer via iTunes or to iCloud then it may be possible to restore your phone's contacts ... otherwise, you may be out of luck.
