PhoneGap is a free open source development tool and framework that allows web developers to take advantage of the powerful features in the iPhone SDK from HTML and JavaScript. It is written in Objective-C and allows developers to embed their web app (HTML, JavaScript, CSS) in Webkit within a native iPhone app.

PhoneGap is developed and designed by Brock Whitten, Rob Ellis, freelance designer Colin Toomey and Eric Oesterle.
