I recently bought an iPhone 4, but I never really had much of a chance to make use of the video recording features to make a movie.
Today I was bored, so I decided to use my iPhone to make a movie out of some of the videos I recorded at the opening of the Apple Store in the Lincoln Park neighborhood of Chicago. I downloaded iMovie and set to work, and this video is the result.

Note that this movie was completely recorded, edited and uploaded using my iPhone 4.
