We wanted to make sure you saw Bas Berck's Pocket Architecture Guide for the iPhone, covering 165 architects in over 270 international cities. Using GPS, the app will recognize where you are and lead you to interesting buildings nearby, giving you some background tidbits, preview images, Google Street View information, and contact info so you can check hours before you go.

The app includes classic icons by Le Corbusier, Niemeyer, Koolhaas and Sanaa and lesser known gems by Kurokawa, Arquitectonica, and Böhm and Tange.

Not groundbreaking exactly, but pretty useful for design enthusiasts. Plus, it's always nice when the iPhone can be used to enrich one's experience of the city, encouraging exploration and discovery of one's surroundings.
