If you did a quick news search on Apple this week, you could easily conclude that CEO Steve Jobs took the stage Monday morning, talked for 20 minutes about a new 3G iPhone, then called it quits.

Most of the opening act’s attention was focused on the iPhone software development kit and the possibilities the platform has opened to developers.
