As of now I don't plan to preorder the 3gs at either at&t/apple, but I plan on going down there myself friday morining to buy it. I have on me $280 in cash that I plan to use to buy the iphone. With the past 3g news of apple refusing cash for iphones, should I take my chance and buy it with cash at the subsized price of 200 or desposit the money into my moms account and use her card to buy it? As for my family plan question. Right now there are 3 lines all connected to my moms account including mine. My moms the only one with the data plan since she has the blackjack, and the other two lines are regular fliphones. Also on the account is the $30 unlimited texting family plan. So if I were to buy the 3gs on friday, would the only added cost to the monthly bill be the the data plan on the iphone?
