Mp4s are essentially a media container, so they can contain music, video, and text, while mp3s are restricted to audio. I think Apple products (iPhone, etc) can play mp4s.

All smart-phones that play video and music are mp4 players, so is the iPod touch, the iPad, the Zune and all other handheld devices that are made for playing music and video.
