Does any one know how to use iPhone (any version) as a web cam. I don't want to use WIFI connection as there as some apps that just do this. I need USB connection so that I may save some bandwidth and the connection via USB would be smooth. Do you guys know any software that just do this. I know there are software for other brand of mobile phones. Thanks guys. PS: sorry for posting this is general forum, should have posted in mobile section.
