my wifes phone is with Verizon wireless and i thought ill move her to my AT&T family share plan when white iphone 4 comes out (she only wants a white iPhone 4) .. since it will be a while before white iphone 4 is out. i was thinking of bring her to AT&T family share without getting into a contract , so i will still be eligible to upgrade on her line when white iphone 4 is finally out. it is possible to just activate a brand new sim using my old IPHONE 3GS with itunes and chose the option to port my number ? if i do it thru itune would i bind my self into 1 or 2 year contact? i want to bring her to my at&T family share plan but don't want to lose my upgrade option. any one ever done this? suggestions?
