I was looking at my upgrade options and total pricing with regard to the Captivate. When I added the phone as an upgrade, not only did it not make me choose a data plan, it didn't even give me a choice to pick a data plan (at the moment I have just minutes and texts). Is this an error on the ATT system or you can get the phone and the data plan is only set up once you use the phone? Because what I am thinking is upgrading 2 lines on my family plan - my line with an iPhone which requires data when you purchase the phone, and the Samsung on the line that will not get Data. I will only use one phone (the Samsung on my line) and sell the iPhone brand new in box. Will that work or will ATT realize when I only have one phone in use on my plan even though I 'upgraded/renewed' two lines?
