The connection is either slow or you need to move around to better your connection. On my PS3, I just pause the video and let it load up more before I even bother to play it. Don't know if you can do that on an iPhone, but it's a suggestion.

Go back and click the video again. It should buffer. This is not the cause of your slow Internet connection, but the problem is the YouTube app. If you use YouTube from Safari it buffers all the way. Another problem is that it plays 1080p videos (which takes longer to buffer) rather than 720p. It would buffer faster if we could turn off HQ, but the YouTube app doesn't have this feature.
