During the development of our marketing plan, we have come across many great iPhone ads and celebrations of AppStore milestones.

When the AppStore approved its 10,000th app for sale last November, this first major milestone was celebrated not only by Apple ads, but others also created their own tributes.

Tap, tap, tap created an amazing mosaic made up of all the 10,000 app icons:

Apple hit 1 billion downloads on April 23rd and very soon after, on September 28th, hit the 2 billion download mark! Geesh.

We’ve all seen the various iPhone ad parodies, but the best one in my opinion is the infamous iStalkHer ad. Note the excellent built-in password decoder.

What are your favorites (for any of the milestones or parodies)?
