Got this to work again on a Touch, may work on the Pro.
After getting a new Touch I could not get this calltone fix to work again, it kept reconnecting to SprintPCS.
I figured out how to get there. Don't mess with adding a calltone connection.
I just clicked edit on the Sprint connection, then selected use proxy, 68.28.31.33. Connected and got to the calltones page and picked a new calltone. Then changed the Sprint connection back to no proxy.
Looks like you have to do it every time to get there, even after saving the calltone page in favorites, with no proxy it comes up "your session has expired" then goes to the not authorized page.
