Today an email was sent out by Apple to all the iOS developers stating a new rule which makes it mandatory for all the developers to submit their app icons with a high resolution of 1024×1024 pixels.
Quote from the email:
Starting in July, newly submitted iOS apps require high-resolution icons and cover art. Large icons and Newsstand cover art must have a minimum resolution of 1024 x 1024 pixels. To change your app icons or cover art, go to the Manage Your Applications module on iTunes Connect. For more information, see the Custom Icon and Image Creation Guidelines in the iOS Developer Library.
This new rule is being enforced on developers to make the app icons look more beautiful on the new iPad which supports a Retina display of 2048×1536 pixels.
