I'm in Australia and I think there's a law that carriers need to keep an amount of 3G coverage. So we will likely lose 4G coverage before 3G. Regulation FTW!

I think it might only be around for another couple of years -- Telstra is switching theirs off in 2024, and Optus is pretty soon too.

Government-granted spectrum monopolies... two wrongs make a right I guess.

I'd be very interested in a dumb phone that works in North America.
