Sod the Enterprise features, what the iPhone needs is a really good
game - something it can do and that pales on other devices.  Trism,
spotted on YouTube (you can see the video after the cut), might be
just the thing: ostensibly a basic colour-matching puzzle, the game
uses both the touchscreen, to move rows, and the iPhone's
accelerometer (which normally adjusts the screen orientation depending
on which way round the cellphone is held).  In this case, triangles
fall into open space following the direction of gravity fitting to the
orientation of the iPhone.

That silence are all those who can NOT play the game on old hardware
used by the cellular industry. The cheering are those with an iPhone
who are clapping with glee.
