I currently have 2 phones on my plan, both unlimited data and neither are ready for an upgrade. I paid full price for an iPhone for me, and for my wife I am wondering if I can do the following. Buy an iPhone on launch day as if I am adding it to my plan as a new phone and pay the $199 for it. Then after a day transfer the new iphone to my wifes line and throw a dumb phone on that line. therefore I don't have to pay data for that phone since it is not needed on a dumb phone and it will just tag on top of my current 700/month talk plan and only cost me $10 for a new line? Am I base here, if not can you please correct me? Thanks !
