Here's a fresh Apple rumor in the run-up to MacWorld: a TomTom GPS module for the iPhone. We just received this supposed photographic "evidence" of said device from a Dutch tipster. Our take? Might be, might not. TomTom is a Dutch company and a righteous, straight-talkin' Dutchman would never tell such a fib, would he? On the other hand, that device is clearly not in a car heading to Rotterdam. Still, it could be a route demo and that stretch of highway (A13/E19) is a favorite for internal TomTom validation studies. Surely a move towards GPS is a logical next step for Apple -- particularly after that little VW concept. And with Apple on the verge of opening the iPhone to third party developers, well, anything goes, eh?

The picture does look fake though.

It has been confirmed as fake, too bad. :(

Yeah, I doubted it, but good to know it wasn't true.

IT's on a frickin' wood table. How is it real? 100% fake.. 9to5mac confirms it.

Fake and too good to be true

The tomtom one is fake but not too good to be true - there is a real open-source dock connector gps in development at partfoundry.com

That answers my thread over in the tool chain section, but what exactly does the micro controller do?
