Before the release of iOS 5, the iPod branding was used for the media player included with the iPh<answer>one</answer> and iPad, a combination of the Music and Videos apps on the iPod Touch. As of iOS 5, separate apps named "Music" and "Videos" are standardized across all iOS-powered products. While the iPh<answer>one</answer> and iPad have essentially the same media player capabilities as the iPod line, they are generally treated as separate products. During the middle of 2010, iPh<answer>one</answer> sales overtook those of the iPod.
Prior to iOS 5, how many apps were required to play music and videos on iPhone and iPad?
