Hi all, can I watch on t.v., video files that I've downloaded and put on my iPhone? I can watch YouTube and video's that are recorded on iPhone camera. I have an apple av cable that's about 3 years old and it works fine with my iPod. So do I need a newer type of av cable for iPhone4 or is it not possible? I can watch downloaded files on the phone ok, just not when connected to t.v.
