How do i change my youtube username using my ipod touch?

[Apparition Dude]

My ipod touch is 2nd generation and it is on ios 4.2.1 firmware
I wanna change my youtube username because i used my real name as a username
I don't want anyone to know who really commented at videos
That's why i used this username in my yahoo "Apparition Dude"
Please guys
Please help me i don't want anyone to know my identity
The reason why i used my real name as a username is because i thought...
Just to be quick i thought it was like twitter
You use a username and your real name as the one that has "@" as the first letter
Thnx guys

At tge bottom it says "Full Site" or "Classic site" find one of those two ande touch it, I think you should know what to do from there. Cause you cant change it in mobile version or Youtube App.
