Most iPhone apps UIs are a mess because they include multitudes of interactions (tap to open a panel, slide up to open a panel, slide to the side to open a menu), and layers upon layers of panels without an easy to navigate back and forth. It's hell.
One UI that solved navigation in a satisfactory way is Windows Phone. Sliding sideways to navigate back and forth, and expanding details in place on tap just makes sense.

Not sure what your point is, since the mode of interaction wasn't the problem with this app. Trying to start a WinMo vs iOS war, perhaps?
