Lecture 15 from the Stanford University iPhone Application Programming class was hosted by Justin Santamaria from Apple. Justin covered the photo picker, Core Location, and accelerometer topics during his presentation, none of which were particularly pertinent to my current projects.
Unfortunately, Justin did not show live demos of these components, which is understandable considering the fact that the simulator has limited support for these components. The code snippets in the slides should be sufficient for getting these things up and running.
At the end of the presentation, Justin also covered some hints on maximizing battery life on the platform.
