No. They clearly had reasons to remove the headphone jack. I'm only addressing the mistaken assumption that there was just "extra" space left in the phone. If you're removing the altimeter/barometer conduit, you're essentially removing the capability for the altimeter/barometer to remove air and balance pressure. Since the original phone was waterproof, this was a necessary piece.

The "new phone" no longer has a working altimeter, is not waterproof, and has major structural issues now. Anyone saying that there was just extra space there is being ignorant of the facts shown or is being intentionally disingenuous for some reason.
