Well I’ve been having trouble with youTube on my iPhone since I bought it. Videos where taking forever to buffer and where really unwatchable. I have a Netgear wgr614 v6 Wireless router which was set to b & g for wireless. After endless testing and troubleshooting I have found that if I force the router into B only mode, although I take a wireless performance hit, youtube on the iPhone is perfect. I really don’t know why this is, maybe apple tried to tweak their 802.11g protocols too much for some routers. Anyways a quick fix that works for me. If your youtube on the iPhone is going slow over wireless and you need a fix, try setting your router to Wireless B only.
I will keep you updated if I find out anything else.
