First of all, you require BIS (BlackBerry Internet Service, or a BlackBerry data plan as some people call it) to access anything over Wi-Fi. Do you have BIS on your monthly plan with Vodafone?
If you don't, go no further until you call Vodafone to get set up with it. You can surf via Wi-Fi with your Data Services turned off, but you have to have that BIS in place before you can even think of getting anything useful over Wi-Fi.
I hope I've been helpful to you.
