actually, both the iphone 3g and 3gs were first spotted 'in the wild' by people noticing unusual user-agent strings in their webserver logs. seems uncharacteristic of apple, which is normally very secretive about unreleased products, but it happened.<p>i can't find the right search terms to google up supporting evidence, but i remember hearing about this in one of the apple sites i read: ars technica, tauw, etc.
