Apple -- on the verge of celebrating its 1 billionth App Store download -- has pulled a controversial application called "Baby Shaker" from its virtual store shelves that generated public outrage.

The application, from Sikalosoft, is a game that involved shaking the iPhone vigorously to make a crying baby on the screen stop crying. Two red X's appear over the baby's eyes when you "win." The application first appeared on the App Store on Monday.

The application's description started: "On a plane, on the bus, in a theater. Babies are everywhere you don't want them to be! They're always distracting you from preparing for that big presentation at work with their incessant crying. Before Baby Shaker there was nothing you could do about it." Clearly, another example of an iPhone app that could get you in trouble.

The application review website KRAPPS gets credit for calling out the application and spreading the word online, such as through Twitter.

The Sarah Jane Brain Foundation expressed disgust over the application and issued a press released titled "Something's Rotten at Apple" that calls out the company for allowing the program to show up on the App Store.

Marilyn Barr, founder of the National Center on Shaken Baby Syndrome and National Advisory Board member of the Sarah Jane Brain Foundation, issued this statement:

"Not only are they making fun of Shaken Baby Syndrome but they are actually encouraging it. This is absolutely terrible," Barr stated Wednesday afternoon.
