It basically breaks down to 4 simple letters CDMA. It would be like
having to support non
hardware on Mac OS. I don't think they'll do it. T-Mobile in the other hand thats a maybe, since they are on a GSM network. But as for Verizon and Sprint, I think not. Even in Japan they went with SoftBank which I believe is GSM even though NTTDocomo is the largest carrier there which is on CDMA or PDS basically not GSM.
