Vodafone told me I was able to upgrade one of my Vodafone numbers and this could be to an iPhone. They said that I would be able to choose a plan and then get an iPhone, but my son would like the iPhone, so I wanted to know, would I be able to upgrade to an iPhone, change my iPhone internet to normal internet and change his BlackBerry internet to iPhone internet (I changed the BlackBerry internet to iPhone internet before by accident) to let him use the iPhone with no hidden costs? Vodafone have really confused me as some advisers are saying no, some say yes!
