The Sony Ericsson Developer World now has RSS feeds available for its content. There are three feeds, latest news, mobile Java 3D, and latest documents, making it much easier to keep up with news and other updates. Obviously the content is developer focused, but interested users might also want to take a look. For example this document is a case study on the Opera web browser on the Sony Ericsson P910.
