Okay so my dad currently pays a family plan that has four lines on it (1400 minutes and unlimited msgs), but my current phone can be upgraded now. Our whole family has the basic phones, nothing fancy. I'm 17 and fortunately got a job and Ive been saving up money to purchase and pay for my own phone now. So if I get an iphone will the family plan remain the same only that I would have to pay more for the 2GB data plan right?

Cause theres this new share everything plan that costs $40 and Im confused wether or not that will be charged on the monthly bill if I do get an iPhone. Im confused D;
