> "just use a second phone" cannot be the answer
Not That i want to kick the can down the road, but the ultimate solution (barring actually fighting for our privileges over the systems we buy) is to have that second phone, and control it either via vnc, or via a kvm which presents vnc. I know, its really absurd, complexity wise, what with tunneling and figuring out where to house said setup. However, the latter is ultimately transparent to the phone, outside of allowing a second monitor/hid to be connected to it. You could, given a VNC client then go ahead and control it via laptop or another phone.
It's not a solution because VNC is already nerfed and will be the first thing to go, if people try to embrace the idea.
Providers of all the service types aren't driving this because they believe locked down phones are a Good Thing. They're driving this because they explicitly don't want you to do the very things you'd want to do with your VNC idea.
