Hello, I just got the 3GS today with Telus (I'm SO happy.). I was wondering, how do I turn 3G off and just use my home's wi-fi, so I can watch YouTube without worry? I looked on the Apple website and they say to go under Settings - Network. I don't have a Network thing. I have: Airplane Mode Wi-Fi Carrier And so on. I think if I join a wi-fi network, it automatically turns my 3G off, but I want to make sure. Thanks!
