well you know that you are using wi-fi when you turn off the the mobile network and turn on the wi-fi connection. Oh I forgot to say this before. If you were on an egde connection in the regular browser and wanted to use the Wap browser. You have to close the entire browser before starting the Wap browser. So first close the browser and go to Wap browser hit the bberry button and go to the mobile youtube site. It will work. I tested it. Sorry for the lack of info from before. Let me know how it goes.
