Whenever I upload a picture to facebook, it goes to my "mobile uploads" album, as expected. However, it doesn't publish to my wall or in anyone's news feed, so the only way a friend can see it is if they go into the mobile uploads album from my page. I've seen others' pictures on my news feed that have been uploaded "via facebook for iPhone". I can't seem to find any settings that are applicable...help?
