In your example http://twitter.com/statuses/update.xml is this page still valid or has twitter made changes. When I use your example with my username and password I get the error <error code="34">Sorry, that page does not exist</error>

New to this so was wondering if twitter has made changes to their structure that breaks this?

Regards
