Today I tried to send my old iPhone4 to a friend in Australia. The post office told me that I could not send it because of the battery. They told me I would have to remove it from the phone but then it could still be in the same package. Has anyone had experience with this? Seems to me if I had told them the battery was out of the phone I would have been fine. I'd really like my friend to get the phone but I don't want customs to take it. Any advice?
