Yeah so while using my iPhone, every now and then on YouTube the videos would be REALLY messed up. Like my screen would start flashing green and the video would freeze and all this random crap. I first noticed this at a friends house, then again at my girlfriends house. Both times I was on WIFI. So I tried watching the same video over and over again, on EDGE and then on WIFI. My YouTube videos ONLY mess up when I'm on WIFI, everything else works fine. Its not that big of a deal to me, but I was just curious if anyone else was having these same problems? And would it be worth it trying to get it replaced? It seems that the videos load fast enough on EDGE for me to be too worried about this issue.
