Sharing contacts with photos in an Iphone

Today I discovered that iPhones cannot forward or share a contact that has photos on it. I am working as a technical support for iPhone and I just spoke to a customer with an iPhone 3Gs who happened to have this kind of issue. What's odd is that, he is able to forward a standard contact number and he can send and receive standard picture messages. But the moment that he share a contact that has the persons picture on it, it fails. He also got an iPhone 4. Out of curiousity , I asked him to try sending a contact with a photo on his iPhone 4, and to my surprise, even the latest Apple iPhone 4 does not support it. Well, I guess in the future iphone software release, this can be added.
