Eye-Fi has announced a new set of cards with a new Direct Mode which allows wireless transfer of images taken on your camera (with Eye-Fi on it of course) to your iOS device running the Eye-Fi app. 9-5 Mac has a good rundown.
My only reason for not getting the Eye-Fi card is the monthly cost for their geo-tagging service, however with a vacation on the horizon, I might change my tune :)
Update: Looks like I was wrong about the geotagging cost, some cards come with a lifetime included geotagging service.
