Zelda: you can try the basic old wap2 interface if Blackberry wont handle a full theme. This is a very basic interface with bugger all user options, but it will do the trick if nothing else works. Fombles: with a 240 screen you may prefer the wap2 interface for the moment too.
The link for the wap2 is
this one. Bookmark it, or you can just append wap2 to any forum url.
I've added a link to the wap2 interface in the Reminder Links block in the forum's left column, just above the Theme Changer block.
Wap2 link has also been added to the Welcome block at the top of the site's front page.
I've also made some changes to the mobile theme to make it more usable, but my sat link is playing up at the moment when I try to FTP files, so I'll load them a bit later.
Devious, treacherous, murderous, neanderthal, sub-human of the West.
