Hi su1234, welcome to the BAUT forum.

It would help us to know both where you heard this, and which speed is being mentioned. Jupiter's orbital speed around the Sun has not changed in any detectable way. I'm guessing that your source was referring to the rotational speed of the magnetic field... which if I remember correctly HAS changed detectably for Saturn, but not Jupiter. Others here will probably follow up with details or correct me if I remembered incorrectly.

I think su1234 is mixing up Jupiter and Saturn. Unfortunately, I cannot find the paper at the moment, but here is a link (http://www.nasa.gov/mission_pages/cassini/media/cassini-062804.html) to a NASA page about it.
