Blackberry Internet vs Normal Internet?

Hi All,
I have just bought a blackberry off the internet. I have called vodafone to check that its nit stoken etc etc etc. I couldnt use the facebook ap, as it kep saying i need to upgrade the price plan.
I called them again and asked, they said i need to pay for blackberry internet.
My question is - do I have to have normal internet AND blackberry internet, or is it ok to cancel the normal vodafone internet. Will the phone and internet email finction only with blackberry internet?

Thanks.
