Does anyone else have trouble with YouTube on their iPhone 3GS? I will be at home on my wi-fi connection and will continually have issues with YouTube. I will search for a video, launch it, it will play for a few seconds, and then just stop. The pause button will convert to the play button, but you can't resume the video. Then, eventually, it will just lock up and say "Can't connect to YouTube." Every other app works fine over my wi-fi. This happens at full signal strength BTW.
