Apple has announced that iPhone 4 owners can order a free iPhone 4 case via a special app that's available now from the App Store. The iPhone 4 Case Program app lets you register for the scheme and order your free case on your handset. Click here to download the app from the App Store.

Customers must download the app and launch it on the iPhone 4. Once you've signed into your iTunes Store account or Apple ID, you can select your case from a small selection.
