With all three providers having moved toward, or moving toward data limits and caps on their network, none of these carriers are going to support anything that has the potential to put data on their network in that fashion, but more so, why would they wanna get customers complaining that they downloaded over "WiFi" and found that they went over their data cap - there by forcing the carrier to raise their unrealistic low data allotments?
I mean, think about it.
