MacRumors WAP and Mobile Editions
http://wap.macrumors.com (screenshot) offers a WAP/WML based version of the most recent stories for your WAP-enabled cellular phone. Any internal MacRumors.com links in these stories now link to their WAP-equivalents and are denoted by (WAP), so that cell phone users may browse referenced MacRumors stories with ease.
http://mobile.macrumors.com offers a lite version of MacRumors designed for Palms/Windows CE/etc... (and, of course, any prototype Apple PDAs that may be floating around out there). Again, any internal MacRumors links in this area link to their mobile equivalents.
Note: These versions will not be updated live during the keynote address. Mobile users should point their browsers to the main MacRumors.com page for keynote coverage... as the MacRumors site will convert to the low bandwidth version during that time. Cell phone users will have to call someone with internet access. :)
