I added a new theme to the wiki aimed at iPhone and iPod touch users so that you can read the wiki and quickly flick through stuff without having to constantly zoom in and out and left and right.
Just point Safari on your device to
http://wiki.graal.us/ as normal and the new theme should automatically appear.
The theme is also selectable from your UserSettings page, so if you want to try it on any other devices and let me know how it works, feel free and I might be able to add the browser detection so that other devices use that same theme.
