How do i switch from myspace 2.0 to myspace 1.0?

You can't. The 1.0 doesn't work anymore, and evenif you could switch back, there is no longer a link to the 1.0 editor, and if you directly send the GET request through the URL you get to the editor, but like I said, it's broken. You can't make changes and there's no save link. Also, I forget what the GET request was so unfortunately, I can't help you anymore than that.

easy go to Customize Profile then up the top where it says Profile 2.0 - Customize Profile next to it, it says go back to profile 1.0 its that simple click it and it will take you back, but personally i hate 1.0 2.0 is way way better. but its your choice. you should check out Customize Profile before you go back
