The Remote app allows you to control iTunes and Apple TV using your iPhone, iPod touch, or now iPad over your Wi-Fi network.
Apple says that Remote has now been “fully optimised to take advantage of the large screen real estate of the iPad as well as the spectacular Retina display in the iPhone 4, and new iPod touch”.
Other new features for version 2.0 include support for Shared Libraries on iTunes and new Apple TV as well as bug fixes and compatibility with iTunes 10 and the new Apple TV.
It looks like the icon has been tinkered with too.
You can now download the new version for free from the iTunes store.
