iPhone 4S contacts problem
Hello,
I got my iPhone 4S on release. Was working fine until today when I was sending/receiving text messages. All of a sudden the contacts in my inbox changed to numbers. For example, the name of the contact "Justin" changed to "xxx-xxx-xxxx."
I simply tried to add the number back to the name (which still exists in iCloud) but it wouldn't change the number back to the name.
Suggestions?
iPhone 4S, iOS 5
