» GoodReader (pdf reader that allows opening big files) – App Store

DataCase is a upcoming AppStore application from Veiosoft that will allow you to use your iPhone or iPod disk as a wireless external disk and file-viewer. The application will be released the 27th of july and i think this will be one of the top-sellers in the App Store (if it will be allowed). The application works with (Mac, Linux, Pc) and needs no upload program or server.
