My mobile users when they view the full version of the site they can not see new messages come up. I have it updating every 15 seconds, but it never does on a mobile device. So they have to keep refreshing to see new messages and they can't scroll either. But scrolling issue is just a lame webkit issue really.
I do remember long ago when on my Palm Pre it did pull in new messages after a while, not so anymore.
But if I view the "Shoutbox Management" from a mobile device it does automatically show new comments. Any ideas?
