Yeah - I don't get the point of this thread.
My iPhone 4 was a decent camera, for a phone. What it was not however was a useful phone or a data transfer device and it went back after just three weeks (think antenna gate).
My HTC Android phone does not produce images of the quality of my iPhone, even though the pixel count is greater. That just proves that there is a lot more to a quality sensor than how many pixels it possesses.
But my Vietnamese DA* lenses produce stunning images mounted on my K-5 - at least in my hands. If you are making better images with an iPhone than with a K-5 I suggest you sell the K-5 and find a new hobby.
