iPhone Webbrowser Application

We need a Application, which runs on Apple iPhone (- Firmware 1.1.4) and iPhone 3G (Firmware 2). This Application should contain only a Webbrowser Instance with no controls,buttons, no URL-Bar etc. - only a maximum size White Space. The principal idea is to have a application which gets the interface from a webserver. The Application needs to load a XML-Configuration from the server, which contains: - URL (Which URL should be displayed on Startup) - Name (Title of the Application) - Button-Text (String) of the Return-button - Loading-Animation Gif-URL Behaviour on "new window": if a link is opened in a new window (target=_blank), the application should display this weblink in a new instance of this application, but: this new window has to overlay over the main window, this new window should have a button on top with the label "return to..." which is delivered by the Config-XML on startup, there should be only one "newlink"-Window (links and newwindow calls in the "newlink"-Window get opened in the same). The Application should display a "loading" animation after click until page is loaded. This Animation is a gif (or something else...) and is set in the Config-XML loaded on startup. Important: Cookies should work, the Webbrowser instance should be a instance of the lokal installed safari if possible. Of course we need the sourcecode and all files.
