iMovie
First time i have actually entered into one of these contest. I use my iPhone (like everyone else here I imagine) to capture videos of the family. I actually have video that i recorded of my daughter being born that i captured on my then current 3GS. It would be cool to take all of that video, from birth to now, and document her life up to now, and iMovie on iPhone would be a great start, since that is where all of the source is (i'm on a iPhone 4 now of course)
