Do 3GP files use AAC or something for audio? If you have QT Pro you have
license to encode to such ONLY via the QuickTime player application. If you
obtain license from MPEG consortium or whoever else holds the respective
license, you can then contact Apple to get some QuickTime SDK add-on to be
able to encode to the respective format too
