An iPhone app called "Baby Shaker" has drawn criticism from children's rights groups and parents. Apple has removed the app, but the groups want to know how it made it on the store in the first place.
Apple posted a Web page counting down to the one billionth app downloaded from the App Store. The company has lots of prizes to be won when that goal is reached.
