Well, it seems that with the latest updates that I did just the other day, I have the option of using some Mobile styles. This is an option that you will need to change under the User Control Panel -> Board preferences... "My Board Style".
I've enabled it as a VERY basic style, but should be a little more friendly for browsing with a mobile phone. I will eventually make some more modifications so that it still has a bit more of a BD.org feel. Also, I offer no support for issues related to that style. It's too new, and not something I'll have time to spend debugging problems for. Hopefully, it will address the needs of those wanting to access via their mobile phone. Personally, I can't stand reading anything of significant length on my phone.
Cheers,
