John - I'd doubt it. Doesn't make sense from the standpoint of Apple's product line. The iPhone is supposed to be the pinnacle of the handheld stuff and therefore will have the best features. The flavor of GPS in the iPhone is A-GPS which means Assisted GPS - it uses cell phone towers to give an initial fix to the phone and to reduce locating time through the GPS satellites. Obviously, a iPod Touch would have no cellular capability which would mean that they couldn't use the same chip set. They certainly could develop another chip set to install in the iPod Touch but like I mentioned before, it doesn't seem to make sense financially from Apple's standpoint. Indeed, it does bring up the question of where does the iPod Touch stand in Apple's lineup given that with the current listed prices, the iPhone is actually cheaper than the iPod Touch.
Maybe Robert's heard differently.
