I'm sure we've all seen the video of the Wii controller working on the N1. Is there software that will allow sync and button mapping for the PS3 controller?
It's actually possible by using bluetooth. There are programs you can use on your pc to do this. Do you want to control your phone with the controller?
I'm assuming the Android phone would have to support the proper Bluetooth profile. But, that's just the first step. There likely needs to be an app written to support the controller itself.
