Not sure what time it comes on, so you will have to look.
The channel that sonic x is on 4 fios is channel 12 kk 
It did come to citv in 2004-2006 but i dont think it will come back to any channel in the world. If you really want to watch Sonic X you can buy the volumes containing 4 or 5 episodes. There are 13 volumes in Sonic X I think.
