Well, the 'pda style" Reggie added (more or less at my request) is certainly easier to use on the 770, but it is in no way the best that can be done for mobile devices with vBulletin.

The layout on the 'view new posts' page (and others) is a mess, with thread titles wrapped and piled vertically atop one another on the left, and most of the space unused. Generally there is a lot of (textual) info lacking (such as post timestamps, last poster name etc.) Also no way to go directly to a thread's last or last unread post...

Other PDA-related sites have more functional mobile versions of the same vBulletin, so it's possible (but perhaps costly, as I think it is commercial software).
