Hi i have a blackberry and at the moment i can only use twitter and whatsapp connected to the wifi. When i top up and gain internet data, can i use this to use whatsapp and twitter when out and about or will it not work? If that doesn't work do i have to pay the 5 pound for blackberrys internet service? But is there a way i can deactivate my bbm because i do not use it anymore?? Thanks
