I am going to give my wife my 4. Apple will make me activate the 4S before I leave the store. That will kick my wife's 3GS out. What are the steps to get the 4S switched over to my line and get my wife going with the 4? Call AT&T, have them switch IMEI numbers? Can my wife use the SIM card that's already in my 4? The SIM card in her 3GS will obviously be dead and it won't fit anyway. I want to make sure this is smooth process. Thanks!
