Hidden Contacts
I used to have a friends name and phone number held as a contact. When I access Contacts, either directly via the Contacts App or via the Phone App, the name is not displayed. The Group displayed is All Contacts. However, when I use the keypad to enter the phone number and press 'Call', the contact name is displayed.
I have 190 contacts displayed in the phone's contact list but I would estimate I have another 30 or so that are not displayed but show the name if the number is entered manually.
How can I recover these contacts so that they display properly?
