Showing contact name with received SMS from Google Contacts

Question

For those of you who have linked your Google Contacts to your iPhone, when someone sends you an SMS did it display the person's name or did it simply display the number?

Because, although I have linked my Google Contacts to my iPhone, I can only access my contacts when I go Contacts -> Groups -> Google Global Address List -> Search.

When someone send me an SMS, only the number is displayed and I have to go Contacts -> Groups -> Google Global Address List -> Search to search for the number and see who it is.
