Ok then, have a look through this thread. It's about using 3GP converter & 1337 gives some really good instructions plus screenshots. That's how I found out how to use 3GP. There's a link for download somewhere there as well. Have a try with that one & see how you go...it's really easy to use.

Just remember that if you haven't changed the default location of your saved files (where your downloads live), your files will be here:
C:\Documents and Settings\your username\Shared.
So that's the place you have to look for files when you want to add them for converting, or add them to iTunes etc.
