It does sync with my yahoo address book, but I don't have any of my contacts numbers in there, just email addresses. I did back up my phone and have been searching all through iTunes for my old contact book with all my numbers- epic fail! Would you have any idea where they would have stored it?When you sync your phone where do you sync your contacts to? Mine sync with my yahoo address book.
Next to "All Contacts" there should be a button that says "Groups."the top already says "all contacts" so I don't think there are any "groups.
but why did this happen at all, just randomly? it's never happened before. I used to sync all the time and all my contacts would sync over from my computer to my phone. Ive been doing it for years. what changed?
