I bought my iPod touch two hours ago and I've spent every minute since totally baffled. Quite simply, it doesn't work! I've downloaded a new version of iTunes. My iPod is connected to my PC through a USB cable, but it's not having it. When I try to turn on the iPod, I get a symbol of the USB cable with an arrow pointing towards the iTunes icon. Pressing the screen or the other button does nothing, and after five or so seconds the screen goes blank. What the hell is going on?!
