Blackberry email attachment handler

Hi, I need a blackberry auto run app. That installs an attachment handler for .mobi and .prc files. Blackberry auto run application It installs an email handler of .mobi and .prc files. When the user selects this type of file in the mail it should ask if he wants to save it, then it should copy the file to the sdcard in the directory kindle\eBooks or the directory eBooks whichever one exists. In case they don't exist ask the user to install the amazon kindle app or the mobipocket reader app. The file will always be saved with the extension .prc regardless if it comes with the extension .mobi . It will have a small gui with the possibility of stopping the auto run.
