gonemob, I don't know of an app for that, however, this process will work:
-Backup your device, complete backup with Desktop Manager. That will create a "*.ipd" file on your PC.
-Download and use this app on your PC
Free download ABC Amber BlackBerry Convertor, convert IPD files to CHM, PDF, HTML, Word, Access, Excel, CSV, IPD Extractor
That should do what you need.
