i want to know if we must have a data plan when we are using an unlocked Verizon or Sprint iPhone 4S on AT&T (by using gevey sim or something like that).
does AT&T automatically recognize even cdma versions of the 4S from its imei (and put them on a data plan)? or is it up to us to add appropriate data?
thanks in advance
