I find it amusing that you would complain about how overly complex android is... in a thread about an overly complex tethering app that requires an instructional video to get things working.
What's even more amusing is the tethering built into android is like a 1 click deal and ur done.
The process is the same for both OSs on AT&T (PITA if you want it to be free) and the same on other carriers (no charge = "like a 1 click deal and ur done").
This setup took me 3 minutes.
