Rolls-Royce’s new Ghost is about to go on sale and in the lead up to its arrival the bespoke British automaker has announced today that its first app for iPhone and iPod touch is now available on the App Store. The app allows potential customers and enthusiasts to configure their own 2010 Rolls-Royce Ghost--and best of all its free.

The Rolls-Royce Ghost app allows users to choose from many thousands of design combinations available to Ghost customers at dealerships. Available exterior options include twelve standard paint finishes, three different wheel styles, visible exhausts as well as a Silver Satin bonnet--an option exclusive to Rolls-Royce Ghost.

The car’s interior can be specified in eight different leather colors and five veneer designs, including contemporary woods such as Dark Wenge and Malabar. After designing their ideal Ghost, users can save their designs in a virtual garage.

The new app also provides a gallery of Ghost images and films as well as a function to search for the user’s nearest Rolls-Royce dealer. For users with an interest in the technical details of the car, the app also features a specifications section.

The Rolls-Royce Ghost app is available from Apple’s App Store and is designed for the iPhone and iPod touch.
