If you think about it, Apple doesn't make much of any content for the iPod. They don't make music or movies or music videos. About the only content they do make are the built in games and some television ads. In fact, do they make an Apple Store locater for their computers?
I have been using the one created by eric quintero, but he discontinued it several months ago! I was actually wondering why there wasn't something made by apple since people kinda need to know where they exist while on the go! here is the best one so far (may not be a complete list!) enjoy!
