We’ve been working for a while on our site. There have been a lot of content updates, with new pages for specific customer types: carriers, device manufacturers, mobile web providers, and mobile application providers.
We are working on building a mobile design resources page. This is very much a work in process. In the meantime, our old links continue to work.
