How to watch video on iPhone in Widescreen Format

When I walked on the iPhone forum, I often come across the same problem of the iPhone users, they are annoyed with the problem why the video on their iPhone are always narrow. How can they view the videos in widescreen format?



As we know, iPhone is a line of Internet and multimedia-enabled smart phone designed and marketed by Apple Inc. An iPhone functions as a camera phone, including text messaging and visual voicemail, a portable media player. You can enjoy your favorite videos on its widescreen anytime anywhere as you like. While do you have the same trouble like people said in the forum?
