My contacts seem to have disappeared. I signed up for iCloud to backup my phone, performed a backup, and a little later when I went to make a call, I received a message that I had no contacts in my contact list. I didn't do anything to intentionally delete all my contacts, and I was never skaed if I wanted to perform such an action. I'm thinking they're somewhere on my phone, but I can't find them. Any suggestions would be greatly appreciated. Thanks.
