Each time I reset my phone I get a message "Your myFaves contact has been updated" and it duplicates my favefive address book entries. If I delete them then next time I reset it duplicates them again; if I don't delete them than next time I have multiple duplications of the entries.
It's nothing stopping use of the phone but it is an irritation.
Is there some way to stop this or some setting I've changed that shouldn't be changed?
