Write an iPhone application, using Adobe Flash Builder

Hi, I require a coder to develop a mobile application, using Adobe Flash Builder only. Ideally, you will develop the app so the logic and the User Interface is separate, so other devices can be targeted in the future - at this stage just an iPhone interface (portrait) will do. In terms of using the program: 1) The application is loaded 2) A list of categories appears, a user clicks on it and another list of child categories appears, or resource links. This is generated from XML Files. Each node should have the name along with the xml file for the category/resource link. There should also be a button to go back. 3) If a user clicks on a resource link the appropriate xml file is read, which will then load a page in a web form. They can close this and return back to the category
