Im on the share everything plan with the iPhone 4s. I put myself of the share everything plan in preparation for the iPad and iPhone 5 which I want to add to my account so the wife can have a shared account with me. Anyways I went to pre order the iPhone 5 as an additional line and I need a security deposit of $400. I have had the iPhone for a year in october and when I first opened an account I had to pay the deposit. I was new to the country then so that was fine however they are asking me for an additional deposit so they want in effect a $800 deposit. Can I phone them up and explain that I'm due the deposit back and can I not just use that money as deposit for the additional line?
