iPod Touch Will Not Connect to YouTube
One of the most common problems that users have with the iPod Touch YouTube app is one based on connection. You will not have permanent connectivity as you will with the iPhone's 3G network, which means that you have to actively connect to Wifi networks to be able to get access to the Internet period. To do this you have to first locate an adequate network and enter the appropriate password information and when you come in proximity to that Wifi connection then you will automatically connect to it.
If your iPod Touch will not connect to YouTube then you should first dial into this Internet connection and make sure that it is adequate. If it shows that you are connected and you still do not get YouTube connectivity then first check another Internet dependent app, such as the Safari web browser. If there is no Internet connectivity then you should disconnect from the network and initiate a reconnection.
Though it may seem counterintuitive, sometimes if your Date & Time are not set to current it can can cause undetermined issues. When your iPod Touch will not connect to YouTube then you should ensure that you have the accurate Date & Time, which is often overlooked since it is not automatic in the way it is on the iPhone.
Another issue that could be preventing the YouTube application from working are the Restrictions that may have been sent, especially since YouTube can be targeted directly. Go into the iPod Touch's Settings and select General, which is directly above Music. In here go into Restrictions, which will require you to enter in the Passcode that is associated. Here you can see if YouTube is set to restriction, and you can either turn it off specifically or Disable Restrictions in general.
