The thing is, I don't even need it to unlock my phone really. I just want it to do whatever I ask it (give or say the response, turn on the lights, etc). It can do that and stay locked as far I am concerned.
For things like Navigation and other things, the phone would have to be unlocked so that is another matter. But for simple things, I'd like it if it would just answer or act - even if it has to stay locked ..
p.s. There's a thread or 2 out about this already.
