It’s obviously very early on and very cumbersome, but I have successfully got my new iPhone 4S to charge from my old Palm Pre’s Touchstone inductive charger. I may not be using WebOS anymore (sadly), but the spirit of my Pre lives on. My goal is to bundle this up in a nice package that can be easily added to an iPhone 4 or 4S, and look good doing it. I’ll post updates when I’m closer to that goal.
