It would cost them dollars. An IPhone costs < $100 to make. Obviously there's a development cost to it all. it's also easy to suggest that there's probably a feature missing atm :D

Sorry but your estimate is off by 2x-4x (depending on model). You can Google "iPhone bill of materials" for details.

It would be like writing off a stamp.
