We almost always watch the bonus tracks included with movies on DVD. It's fun to see the scenes that didn't make it into the final movie, for one reason or another. We especially enjoy getting a behind-the-scenes look at the tricks and techniques the crew used to shoot a particular scene. Want to know how they pulled off that amazing car chase in the city? It's in the bonus track. It's all extra stuff you can skip, but the bonus tracks often contain real gems of information. Watching them usually gives us a greater appreciation for the movie.

Since last summer we've been running iPhone training courses and producing iPhone-related screencast video tutorials. Unfortunately, even in a 4-day course or a 1-hour screencast, you have to leave some stuff on the cutting room floor. Though we're learning new iPhone development tips and tricks every day, they don't all get brought up during a course or warrant a full-length video tutorial. But it's good stuff we don't want you to miss!

So, this week we're rolling out our own series of bonus tracks. These are free, short screencasts focused on a single iPhone tip, trick, or technique that you can quickly apply. We're kicking it off with three tracks. We plan to release a new bonus track every week or so to keep you on top of your game.

Whether you've attended one of our courses or not, we hope you enjoy these bonus tracks all the same. All we ask is that you'd leave a comment once in a while to let us know how we're doing, and spread the word. :-)

Thanks, and enjoy!
