I think it is a good idea, but what about to download the full contact vcard only when it is to be displayed? When we connect we attempt to download the full phonebook which is cached for fast lookup but while ringing we can download the full vcard including the picture. A single vcard should be really fast specially since we are already connected and should have a session active, in any case this would have to be done if the contact is not found locally we should stop any ongoing operation and attempt to search for the phone number. -- Luiz Augusto von Dentz -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
