You can control itunes from iphone by installing Remote from application store. When you start up Remote after associating with a library, it’ll take a second to reconnect. It allows you to sync your iPod Touch/iPhone and the Remote application. Your iPhone or iPod Touch will recognize the iTunes library immediately after installing Remote and you can control iTunes using your device.
