Yes I should have said impractical. I'd hate to think of what a special iPhone would cost just for the Australian market, which is relatively small, should Apple (and others) decide to not foist this on everyone else world-wide. Just come out with different hardware that's easier to hack just for Australia - only to be sold in Australia, and charge appropriately. Make them pay more to be less secure. It would be justifiable if the hardware was different for a smaller market. It's no different than if they came up with their own cellular system that was incompatible with international standards. It would cost more to build for it because it's a small market with unique requirements.
