My co worker has a 5c. He has his contacts synced with iCloud. His contacts are not connected to any of his email accounts either. All contacts have been saved to the phone. A few days ago he noticed that some of his contacts have disappeared. When he uses iMessage contacts that were saved now just show up as numbers and no longer as names. If he types in the numbers on iMessage the name will show but it is grayed out and has an i with a circle around it. Does anyone know how to have his contacts loaded on the phone again. He has also not backed up the phone to a computer either.
