iPhone Photos Askew

Am I the only one who’s taking pictures where the perspective is warped on my iPhone? Perhaps I’m accustomed to the two-dimensional effect of conventional cameras, but from time to time, buildings seem out of whack. Here are some lovely examples:
5th and Washington, Hillcrest.

Ash Street towards the Harbor, Downtown San Diego.

Columbia District, Downtown San Diego.

This one almost seems to be in classical perspective, but is still a bit off:
Core District and East Village, Downtown San Diego.

Please tell me I’m not crazy.
