iPhone File Viewer

We need to have a basic file & folder viewing iPhone App created. The program will browse files and folders on the iPhone within a directory. The files should display the default icons for the file type and have a clean/polished interface. There need to be features to do the following: "new folder", "rename", "e-mail", "delete" The program should be able to open and view the standard iphone-compatible file types, such as .doc, .mp3, .mp4, .txt, etc... We already have the file transfer part of the program, so this is not needed. This initial version of this project needs to be completed as soon as possible and quality is also important.
