With Eric Schmidt, history would suggest you're being naive.
He was on the Apple board until giving Google's Android division NDAed designs for iPhones, at which point Android phones lost the trackball, yes, trackball, and went full touchscreen. He was subsequently removed from Apple's board.
I've just spent 5 minutes googling this claim. It seems totally unfounded. There are stories about how Google engineers, including Rubin, were nonplussed when Jobs first demoed the iphone, because they had no idea what was coming.
There are official explanations for Schmidt's departure from the Apple board that acknowledge the ios/android conflict but do not imply any malfeasance on his part. There are stories that Schmidt even left board meetings when iphone issues were discussed, precisely because of concerns about this.
I'm not saying you're wrong about this, but the evidence for such a claim isn't as obvious as I would expect if it was true.
The idea is simply preposterous. You think Steve Jobs, obsessive about secrecy, would let his main competitor Google CEO know about secret iPhone plans?
