I am currently on a family plan with Alltel. When my contract is up in a couple months I want to get a smartphone but I don't want to have to pay a lot more a month than I already do. If, when my contract was up, I went to an Alltel store and bought a BlackBerry or other smartphone would each line in the family plan be charged the data/voice package price, or just my line? And also, how much would it be? I currently have the Axcess Pass that gives me unlimited messaging and mobile web.

P.S. don't tell me to wait because Verizon bought Alltel, I already know. =]
