I've been wondering if anyone else has this problem, or if it's just me. Not so long ago I noticed that when I try and upload youtube as a webpage on my itouch over wifi, but it doesn't work. Now, I don't usually use the youtube app because I can't look at people's profiles for example, and I feel that it even lags more than when I use youtube mobile in the safari browser. And before this, it worked fine, but lately I have tried but the page just doesn't want to load. My wifi connection is fine, and everything else loads fine. Anyone else have this kind of problem?
Hmm... I tested YouTube on an 8 GB 4th gen iPod touch and it worked perfectly fine over wifi. Try deleting your cache, cookies and history. And restart your device.
