So I know this has been discussed before but I can't find the thread. I'm going to be using a family members upgrade for the new iPhone. Ill then take the phone and put it on my line. The line that has the eligble upgrade does not have a data plan. I just want to be sure I have this correct. Ill preorder on Apple.com and it will tell me that I need a data plan. Ill choose the cheapest data package and choose the new iphone. When it comes, I have to take it to ATT for them to switch it to my line? Will they allow me to cancel the new data package I added in order to upgrade? Or am I stuck paying a data plan on a phone line that doesnt even have a smart phone?
