We are well on our way. The EU is holding the manufacturer liable if a cellphone radio is "modded", thus manufacturers are blocking the ability to unlock bootloaders.

If eventually, that is every phone, then grab a hotspot and get tethering.

I did have a chuckle at the thought of having a cellphone for your (modded) cellphone... but then I thought about it: "meh, yeah... it's not a bad idea. I'd do it."
