Hats off to Macenstein, whose sleuthing efforts have paid off to the tune of 1,300 Diggs. In the newly released iPhone movies, Macenstein noticed the appearance of a mystery application on the iPhone’s home menu. What was originally 11 apps on the home menu is now, apparently, 12. Dun, duh, duuh.

What could be the new mystery app? Are you excited to find out? Who has the time to scrutinize videos like this? June 29 can’t come soon enough. For several reasons, actually.
