What Happened to My Contacts in My iPhone?

Contacts

Episode 1626

Steven from San Antonio, TX

Steven logged into the hospital internet on his iPhone, and he lost all his numbers. It reverted back to an old phone backup. Leo says that's an odd thing. Sync is notoriously troublesome because it doesn't usually know what version is the current, official version. Look at all the accounts the phone is logged into and see what account syncs to the contacts. That is usually what happens. Users wind up logging into a different account, and it wipes out the existing contacts.
