I found a sweet app for Android today for those of you with Droids that tether your head unit to your phone for interweb access.
AutoTether:

This is such a simple app that senses your bluetooth connection from your radio and kicks your phone into tether mode automagically. And when you turn off the car, the BT connection stops and the app shuts down tether mode for you.
Now I can just get in and go. My phone switches to tether for me and my android radio has internet access for pandora, etc.
I have a Nexus 4 for reference. Tethering isn't locked out for me, don't know what might happen on a locked down carrier phone like a GS3 but won't hurt to try.
Just thought I would share something I found useful to make my knockoff experience even better.
