I want to upgrade my iphone to the iphone 3GS and my mom says I can get it but my Dad says NO WAY. What should I say to him to convince him to let me get it????? Any help will be appreciated! Thanks! Edit: I have the money for the iphone 3GS and that's why I need your help. My Dad won't let me spend my own money on it but my mom doesn't care and that's where I need the help. How can I convince him to let me get the phone with MY OWN money?
