this is pretty easy.... search the forum for db2020 file system parser u will get the main2raw and semctool that would make your job easy.
You wont need to connect your fone to get the complete file system. Just provide the main2raw with ur filesystem (.fbn) and u can extract the ifs,trp and other directories.
ill search and post the link soon.
This is the easiest method as u will get the orignal files in a breeze.

If u want to do it the difficult way. Use FAR Manager and the XML Source generator. By this method u will be able to copy one file at a time.
