Really it's unfortunate about the turn by turn and FaceTime for the iPhone 4 but they still need to differentiate the phone because let's face it it's practically the same damn 2 year old phone for $199+ (iPhone 4s)
So it's purely marketing/sales
That said iPhone 4 users - our resale will certainly take a hit![]()
This is the reason they are doing it. You sell your iPhone to someone, and they don't get any of that action, other than a new posable iTunes account, with credit card.
Until proven otherwise, they are withholding features on iphone4 purely for financial reasons. Not the first time they have done this, and won't be the last.
