I have a solution that fixes PHProxy's MySpace login without turning off javascript. My plugin also allows your proxy users to post bulletins and send messages on MySpace through your PHProxy sites.
Zelune may be able to login to MySpace, but try to post messages, comments or bulletins. Can't do it. Who would want to use it if they can't communicate? Isn't that what MySpace is all about. If you want your users to be able to use MySpace's features you need a fix to workaround their new code changes. You can find a free fix here: http://tripthru.com/tripthru-tools.php
Login, posting bulletins and messages works under my TripThru Tools. Comments will be available shortly. It's free, so updating after the comments are working is not a problem. If you find it useful, a donation would be nice.
