Hi, I'm thinking of getting a camera connection kit for my ipad2. I would like to use it to connect to an external USB hard disk to backup all my images that i shoot from my camera. As I usually shoot in raw format, it may run out of space soon in the CF card. So I would to be able to transfer to my portable hard disk using iPad 2. Is that possible? I've check with local Apple reseller but they claimed that the camera connection kit is not able to allow me to perform those functions, is it true?
